In this context, organic borazines have emerged as promising molecules useful both as doping units and organic semiconductors, particularly in the production of photovoltaics and organic transistors. However, like most “fine chemical” products, their engineering is generally complex and harmful to the environment due to the need for dangerous reagents, solvents, and harsh reaction conditions. Recent adopted advancements in the manufacturing process, including continuous-flow synthesis and the use of safer, biomass-derived solvents, have been confirmed through a comprehensive cradle-to-gate life cycle assessment (LCA). The study, compared to four batch processes from the literature, identified electricity consumption as the primary contributor to environmental and human health impacts. Additionally, it was demonstrated that adopting a continuous-flow approach, which reduces electricity consumption and leverages safer reaction media such as 2-MeTHF, characterized by an exceptional recovery rate (90%), proved to be an effective strategy, resulting in a notable 11% reduction in emissions. Furthermore, an uncertainty analysis using the Monte Carlo method revealed that energy mixes reliant on fossil fuels increase the impacts across all categories related to human health damage.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"265 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a novel nanofiltration membrane with alternating hydrophilic–hydrophobic functional layers was developed. The enhanced removal and mechanism of typical micromolecular organics, including N,N-dimethylformamide (DMF), aromatic compounds and long-chain hydrocarbons in petrochemical wastewater were investigated. The modified membrane was assembled alternately with polytetrafluoroethylene (PTFE) and polyvinyl alcohol − maleic acid − sodium styrene sulfonate (PMS). The introduction of hydrophilic PMS underlayer reduced the aggregation of hydrophobic PTFE, leading to the formation of uniform and smaller membrane pores (i.e., from 0.45 nm to 0.22 nm). The alternating hydrophilic–hydrophobic layers overcome the limitations of the single hydrophilic interaction and can efficiently remove broad-spectrum micromolecular pollutants (e.g., the DMF removal efficiency is increased by 64.7 %) and decrease membrane fouling by 88.5 %, which compensates for the performance defects of conventional nanofiltration membranes. Moreover, the novel membrane was proven to be effective in treating petrochemical wastewater, meeting discharge standards and maintaining excellent performance stability after six cycles.

However, most hydrogen production processes remain carbon-intensive, and the low volumetric energy density of hydrogen significantly hinders storage efficiency. To reduce carbon emissions during hydrogen production, amine-based chemical absorption methods are commonly employed. However, these methods face challenges, such as low capture efficiency and high energy demands. To improve storage efficiency, hydrogen liquefaction methods have been explored to reduce volume. Nevertheless, liquefaction methods require cryogenic operating temperatures, which result in high power consumption and substantial cost burdens. To address these issues, this study proposes a novel system that integrates hydrogen production and liquefaction processes by introducing cryogenic carbon capture (CCC). In the proposed system, CCC obtains cold energy through integration with the precooling cycle of the hydrogen liquefaction process, eliminating the need for additional refrigeration units. Consequently, the integrated system achieves a 99.99% carbon capture rate, with a 27.5% reduction in overall energy consumption. Moreover, the economic feasibility increased by 7.87%, and the CO2 avoidance cost decreased by 58.5%. The carbon-techno-economic analysis results revealed that the carbon capture penalty can be offset at 52.5% lower carbon tax rates. Additionally, scenario studies revealed that the proposed system demonstrates 41.9% higher economic performance than liquefied green hydrogen systems while maintaining comparable environmental benefits.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"40 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the controlled synthesis of Cu-ZnO catalysts featuring Z-scheme heterostructure remains a formidable challenge. Herein, an advanced, rapid, and controllable photo-deposition method is developed to fabricate a reverse oxide/metal structure, which involves coating Cu clusters with a Cu oxide layer to produce Cu-ZnO catalyst characterized by typical Z-scheme heterostructures (CuxO-Cu-ZnO, abbreviated as Cu-ZnO-PD). The catalyst of the CuxO-Cu-ZnO structure exhibited remarkable thermal catalytic performance and achieved an 89.5 % increase in methanol yield under light irradiation (350–780 nm). Notably, the catalyst maintained structural stability even after the third catalytic reaction cycle. In-situ characterization and theoretical calculations show that when CuxO-Cu-ZnO is irradiated, generating a high-intensity photocurrent, which enhances H2 adsorption on the catalyst surface and significantly reduces the free energy barrier for H2 dissociation by 0.718 eV, thereby promoting H* spillover. Furthermore, photo-assisted thermal catalytic reaction alters the rate-determining step from the initial hydrogenation of HCOO* to the hydrogenation of HCOOH*, thus advancing the methanol synthesis pathway.

Despite tremendous efforts have been made to improve the performance of quasi-2D perovskite LEDs (PeLEDs), previous studies have mainly focused on enhancing the radiative recombination efficiency via phase distribution control or defect passivation of perovskite films. However, an in-depth understanding of the crystallization kinetics of quasi-2D perovskites, crucial for achieving high performance PeLEDs, is still lacking. Herein, we propose the introduction of a strategically designed intermediate phase to regulate the crystallization behavior of quasi-2D perovskite films. It is revealed that the intermediate phase of phenylphosphonic acid (PPA)-PbI2 composite can significantly lower the nucleation energy barrier, effectively manipulating the crystallization kinetics and drastically improving the overall quality of the perovskite films. As a result, the PPA-treated quasi-2D PeLEDs obtain a peak external quantum efficiency (EQE) of 22.74 % along with an ultrapure red emission at 650 nm with CIE coordinates of (0.708, 0.2919), which is among the closest point approaching the pure-red light coordinates of (0.708, 0.292) in display standard of REC.2100 reported to date.

Here, this issue is addressed by developing a novel hydrophilic-hydrophobic conversion strategy to engineer an environmentally robust organic/inorganic hybrid superhydrophobic coating with remarkable anti-soiling properties and pH-induced recoatability. This conversion, achieved through surface chemistry regulation incorporating hydrophobic hydrocarbon chains and aminopropyl functional groups, yields a coating with a high water contact angle (WCA) of 155.4° and a low sliding angle (SA) of 1.3°. Notably, the WCA can reversibly transition to 0° within 15 s under pH adjustment. The wide range of the surface energy variations enables effective recoatability and restores surface wettability in damaged coatings, with an adhesion strength up to 5.34 MPa, allowing for the in-situ reuse of old coatings. The uniform distribution of modified silica nanoparticles within semi-cured epoxy matrix imparts satisfactory environmental durability, allowing the composite coating to retain its superhydrophobicity after enduring various harsh conditions, including 100 cycles of sandpaper abrasion, 70 cycles of tape-peeling, 120 h of water immersion, and 168 h of heat and humidity exposure.
