The channels present within the catalyst layer of MEAs exhibit a disordered configuration, which consequently give rise to low efficiency in mass transportation. This paper presents a novel double-side ordered MEA to improve its both mass transport performance and durability. Using seed-assisted hydrothermal reaction and nitriding treatment, TiN nanorods array was synthesized on ITO surface and the catalyst was uniformly coated onto the TiN support by ultrasonic spraying. After that the double-side ordered MEA was fabricated employing a transfer printing process. The electrochemical testing was conducted to evaluate the MEA’s performance, and results showed that the double-side ordered MEA can generate a peak power of 678.30 mW/cm2 with platinum loading of 0.2 mg/cm2. After chemical accelerated stress test operation, the peak performance degradation was 5%. These results provide substantial evidence for the effectiveness of our developed double-side ordered MEA can mitigate catalyst polarization corrosion. Thus, this study reveals the immense potential of the TiN nanorod array-based double-side ordered MEA could advance the development of efficient and stable MEAs.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140198717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was observed that adding thiourea improved the removal of n-alkanes from the gasoline, and matching results were obtained through the experiments using model samples. Molecular dynamics simulation revealed that the stability of urea complexes increased with raising carbon number of n-alkanes, while lighter n-alkane molecules exhibited lower propensity for complex formation with urea. This finding is in line with the results of DSC measurement at decomposition temperature. Furthermore, infrared spectrum analysis, XRD characterization, and reaction heat measurements indicated that although thiourea was introduced into the reaction system, it did not actively participate in the complexation reaction. In summary, the introduction of thiourea resulted in an increased solubility of urea in ethanol solution and enhanced reaction heat, suggesting its beneficial role in promoting urea complex formation and facilitating n-alkane removal from FCC gasoline.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140156690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, activation of polyaniline (PANI) mixed with wheat straw-derived bio-oil and K2C2O4 at 800 °C was conducted, aiming to understand the effect of potential interactions of bio-oil with PANI on pore development of resulting activated carbon (AC). The results revealed cross-polymerization reactions between PANI and bio-oil during direct activation, which increased the yield of AC from 13.0% (calculated average) to 15.0%, the specific surface area from 1677.9 m2 g−1 (calculated average) to 1771.3 m2 g−1, and the percentage of micropores from 94.3% to 97.1%. In addition, pre-polymerization of PANI and bio-oil at 200 °C before activation was also conducted. Such pretreatment could increase the AC yield from 13.0% to 23.3%, but the specific surface area decreased to 1381.8 m2 g−1. The pre-polymerization formed the organics that were more resistant towards cracking/gasification, but introduced oxygen-rich functionalities. This made AC highly hydrophilic, rendering a much higher capability for adsorption of phenol despite the smaller specific surface area. Additionally, the AC with developed pore structures facilitated dispersion of nickel in Ni/AC and enhanced the catalytic activity for hydrogenation of o-chloronitrobenzene and vanillin.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140056770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In nearly all reports to date, the liquid component consists of only one chemical species. However, unlike traditional solid surfaces, the unique nature of liquid surfaces holds the potential for synergistic and even adaptive functionality simply by including additional elements in the liquid coating. In this work, we explore the concept of multi-component liquid-infused systems, in which the coating liquid consists of a primary liquid and a secondary component or components that provide additional functionality. For ease of understanding, we categorize recently reported multi-component liquid-infused surfaces according to the size of the secondary components: molecular scale, in which the secondary components are molecules; nanoscale, in which they are nanoparticles or their equivalent; and microscale, in which the additional components are micrometer size or above. We present examples at each scale, showing how introducing a secondary element into the liquid can result in synergistic effects, such as maintaining a pristine surface while actively modifying the surrounding environment, which are difficult to achieve in other surface treatments. The review highlights the diversity of fabrication methods and provides perspectives on future research directions. Introducing secondary components into the liquid matrix of liquid-infused surfaces is a promising strategy with significant potential to create a new class of multifunctional materials.Keywords: Active surfaces; Antimicrobial; Antifouling; Interfaces; Sensing surfaces.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/im/d4im00003j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139947332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the challenge of achieving efficient mass transfer between gaseous CO and liquid H2O at the photocatalytic interface under mild reaction conditions hinders the advancement of the photocatalytic WGS reaction. In this study, we introduce a gas–liquid–solid triphase photocatalytic WGS reaction system. This system facilitates swift transportation of gaseous CO to the photocatalyst's surface while ensuring a consistent water supply. Among various metal-loaded TiO2 photocatalysts, Rh/TiO2 nanoparticles positioned at the triphase interface demonstrated an impressive H2 production rate of 27.60 mmol g−1 h−1. This rate is roughly 2 and 10 times greater than that observed in the liquid–solid and gas–solid diphase systems. Additionally, finite element simulations indicate that the concentrations of CO and H2O at the gas–liquid–solid interface remain stable. This suggests that the triphase interface establishes a conducive microenvironment with sufficient CO and H2O supply to the surface of photocatalysts. These insights offer a foundational approach to enhance the interfacial mass transfer of gaseous CO and liquid H2O, thereby optimizing the photocatalytic WGS reaction's efficiency.Keywords: Water-gas-shift; Photocatalysis; Triphase interface; Hydrogen evolution; TiO2.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/im/d3im00135k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139928707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus of this study is on the properties and mechanisms involved in the CO2 adsorption on clean MgH2 surfaces and the role of Co catalysts in enhancing the adsorption process. Density functional theory (DFT) calculations were performed to examine different CO2 adsorption sites on the MgH2 surface, including adsorption distances, binding energies, and geometric parameters. The results indicate that physical adsorption of CO2 occurs on MgH2, with similar adsorption energies observed across the different adsorption sites. The coverage effect of CO2 molecules on MgH2 was also investigated, revealing an increased affinity of CO2 with higher surface coverage. However, excessive coverage led to a decrease in adsorption efficiency due to competing surface adsorption and intermolecular interactions. The orientation of adsorbed CO2 molecules shifted from parallel to pseudo-perpendicular arrangements upon adsorption, with notable deformations observed at higher coverage. Furthermore, the study explores the CO2 adsorption capacity of MgH2 in comparison to other materials reported in the literature, showcasing its medium to strong affinity for CO2. Additionally, the effectiveness of Co single atoms and Co clusters as catalysts for CO2 adsorption on MgH2 was examined. Overall, this theoretical investigation provides insights into the CO2 adsorption properties of MgH2 and highlights the potential of Co catalysts in enhancing the efficiency of the methanation process.","PeriodicalId":29808,"journal":{"name":"Industrial Chemistry & Materials","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139584574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
