However, their structural instability, poor conductivity, and sluggish ion migration kinetics severely limit their practical applications. Herein, an ultrathin electron-delocalized conductive polypyrrole coating was constructed on V₂O₅ (denoted as V-VO@CP) under a unique vapor-thermal environment. The in situ polymerization of pyrrole vapor improves the π-electron delocalization of the formed polypyrrole coating, which enhances the electron/ion transfer kinetics of the V-VO@CP cathode. Furthermore, the ultrathin even conducting coating (thickness of 11.57 nm) enhances the interfacial electronic conductivity of the V₂O₅ host and mitigates vanadium dissolution, thus achieving the stable cycling performance. The ZIB with the V-VO@CP cathode delivers a maximum discharge capacity of 383 mAh g^–1 at 0.5 A g^–1 and 262 mAh g^–1 at 10 A g^–1 with 80% capacity retention after 3000 cycles. These results verify the feasibility of a vapor-thermal environment for developing an efficient and scalable polymer coating of advanced cathode materials.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"6 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, nitrogen self-doped g-C₃N₄ (NCN) with optimized band structure was successfully fabricated by the copolymerization of a mixture including melamine and ethylenediamine. The resultant samples were perfectly applied to the photocatalytic hydrogen production and photodegradation of tetracycline. Characterizations and density functional theory (DFT) calculations identified the introduction of a nitrogen doping site within the g-C₃N₄ framework. The narrowed band gap, limited photoinduced carrier recombination, and rapid charge transfer were attributed to the DFT, optical properties, and photoelectrochemical analysis, which improved the visible light absorption and optimized the carrier migration channel. Specifically, NCN6 exhibited a 13.47 times higher hydrogen evolution rate (3.07 mmol g^–1 h^–1) with an apparent quantum yield of 12.65% at 420 nm and 1.78-fold (82.49%) better photodegradation efficiencies than pristine g-C₃N₄ (0.23 mmol g^–1 h^–1 and 58.79%), respectively. This study offers a straightforward approach to the synthesis of functionalized g-C₃N₄, with the objective of enhancing the photocatalytic activity and elucidating the doping mechanism. Furthermore, it provides guidance for the development of nonmetal-doped organic semiconductor photocatalysts.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"25 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Humidification had an inhibitory effect on C₂H₄ yield at 700 °C, with no impact at 750 °C, led to notable differences in electrochemical performance, and corresponded to post-trial anode compositional differences. C₂H₄ production embodied energy under humidified conditions was estimated to be higher than at dry conditions due to energy expenditure to generate steam. Together, these results suggested that e-ODH processes benefit from using a dry C₂H₆ feed stream. Additional findings include potential evidence of H₂O-induced C₂H₆ reformation to hydrogen (H₂), and iron and iron oxide structures observed in the post-trial anodes may have significance in describing the underlying catalytic behavior.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports an ordered mesoporous silica encapsulated Pd catalyst for the efficient semihydrogenation of aromatic alkynes. In the selective hydrogenation of phenylacetylene to styrene, Pd@o-SiO₂, wherein subnanometric Pd clusters are encapsulated within the well-ordered channels of silica, exhibits a hydrogenation rate that is approximately 13-fold higher than that of the Pd/C catalyst at 298 K. The Pd@o-SiO₂ catalyst with subnanometric Pd clusters shows high styrene selectivity even at nearly full conversion, whereas the 1% Pd@o-SiO₂ catalyst with Pd nanoparticles favors the overhydrogenation of styrene to form ethylbenzene. Detailed characterization indicates that the ordered silica encapsulated Pd clusters modulate the adsorption behavior of phenylacetylene and facilitate the desorption of styrene, which are crucial for enhancing styrene selectivity. Further recycling experiments demonstrate the excellent stability of the Pd@o-SiO₂ catalyst due to the SiO₂ framework, which protects and confines the Pd species against growth and coalescence.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"47 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coupled integrals equation approach (CIEA) is used to provide approximate relationships between mean values and potentials at the boundaries, reducing the number of independent variables. Therefore, in this present work, the GITT approach was applied to solve the two-phase extraction model with carbon dioxide as supercritical fluid by adopting both relationships, the linear Henry’s law and the nonlinear Langmuir isotherm, to describe the phase equilibrium state. The approach used in this study is mainly based on a hybrid solution that combines the CIEA and the GITT methodology. The present method showed excellent predictive capabilities on the effective extraction behavior. Furthermore, comparing the results to numerical ones from the method of lines (MOL) and those from experimental data available in the technical literature showed that the hybrid approach could provide good results while maintaining accuracy and reliability.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"49 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143035076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A liquid mixture of ethanol in water was completely magnetized by permanent magnets with an induction intensity of 0.8 T, and both magnetized and nonmagnetized ethanol–water was used for total reflux distillation in a concentric ring rotating bed (CRRB) that served as a rotating packed bed (RPB). Results showed that the magnetized ethanol–water could significantly and hardly raise the separation efficiencies of the CRRB rotor with malposition and contraposition of holes on adjacent rings, respectively, compared to the nonmagnetized ethanol–water. This demonstrated that the structure of the rotor had a key influence on an increase in distillation separation efficiencies if a magnetized liquid mixture was used. And the gas pressure drop across the CRRB in the distillation also changed with the magnetized ethanol–water, compared to that with the nonmagnetized ethanol–water. In addition, after magnetization, the distillation separation efficiency of the CRRB increased significantly higher than that of the conventional packed column, which meant the high gravity in the CRRB augmented the intensified effect of magnetic field on distillation. Applying a magnetic field for RPB distillation is a novel method of distillation intensification, displaying good application prospects.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"13 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phadke","doi":"10.1021/acs.iecr.4c03408","DOIUrl":"https://doi.org/10.1021/acs.iecr.4c03408","url":null,"abstract":"The recent interest in the production of green hydrogen through water electrolysis is hampered by its high cost when compared to steam methane reforming. To overcome this disadvantage, some studies explore replacing oxygen production with hydrogen peroxide at the anode, which has a higher value. Existing electrocatalysis research primarily focuses on hydrogen peroxide synthesis, neglecting process design and separation. Additionally, hydrogen peroxide’s thermodynamic instability in alkaline conditions and the existence of other ions make the separation difficult. This paper proposes a novel concept for the paired water electrolysis process that can be used to improve green hydrogen production economics through valuable chemical coproductions. Valorizing hydrogen peroxide to sodium percarbonate as the final product was chosen to address hydrogen peroxide separation challenges. An electrolyzer stack of 2 MW was chosen, incorporating a recirculating structure, and a boron-doped diamond anode to enhance the hydrogen peroxide production as the base case. According to the techno-economic analysis, for a 2 MW electrolyzer stack, capital expenditure was calculated as 64.5 M€, operational expenses as 21.6 M€, and revenue was calculated as 2.5 M€, resulting in a negative cash flow of −19.1 M€. Results revealed that the process can be profitable (breakeven point) at a capacity of approximately 308 electrolyzer stacks, which is 616 MW in capacity. A sensitivity analysis was conducted to determine how cost drivers including electricity price, anode price, Faradaic efficiency, price of the products and tax subsidy affect the breakeven point. A breakeven point of 60 electrolyzer stacks (120 MW) was found with a 100% increase in the sodium percarbonate sale price. In comparison, a theoretical 100% Faradaic efficiency in the anode material would result in a breakeven point of 38 electrolyzer stacks (76 MW). Even a more realistic 75% Faradaic efficiency leads to a breakeven plant size of 75 stacks (150 MW). Further, multiple two-parameter sensitivity analyses were conducted to assess the relations between Faradaic efficiency, sodium percarbonate sale price and anode material price. For instance, if sodium percarbonate price increases by 100% and Faradaic efficiency increases to 75%, the breakeven capacity drops down to 13 stacks (26 MW). Despite facing economic challenges for the proposed process design based on available technologies, the techno-economic analysis highlights key targets for future works. It also provides valuable insights into the economic feasibility of simultaneously producing hydrogen and sodium percarbonate through water electrolysis, indicating promising potential for the future.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"27 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These negatively charged atom sites, derived from CuN₄ and InO₈ clusters, form multiple hydrogen-bonding interactions with CH₄, significantly enhancing its adsorption affinity. CuIn(3-ain)₄ demonstrates a high CH₄ uptake of 1.56 mmol g^–1 and excellent CH₄/N₂ selectivity under ambient conditions, outperforming many reported materials. Dynamic breakthrough experiments confirm that over 90% purity methane can be obtained in a single adsorption–desorption cycle. Grand Canonical Monte Carlo (GCMC) simulations and density functional theory (DFT) calculations reveal that the nitrogen and oxygen sites play a crucial role in selectively recognizing CH₄ over N₂, leading to a superior separation efficiency. Moreover, the material exhibits excellent cyclic stability and scalability, making CuIn(3-ain)₄ a promising candidate for practical CH₄/N₂ separation in CBM purification.
