Herein, we report a strategy enabling the synthesis of nickel-iron LDHs with abundant edges (NiFe LDHs-E) based on the use of citrate anions as the structure-directing agent. The edge density is characterized using spectroscopy techniques and its OER performance is compared with that of nickel-iron LDHs with abundant basal planes (NiFe LDHs-B). In alkaline electrolyte (1 M KOH), NiFe LDHs-E exhibits excellent OER activity with very low overpotential (235 mV at 10 mA cm−2) and current densities (at η = 320 mV) up to sixfold higher than those of NiFe LDHs-B. Density functional theory (DFT) calculations confirm the high OER activities ascribed to the abundant side-plane edges with optimal strength of binding of OER intermediates.

This study investigates the performance of nine metal oxide catalysts (SnO2, SiO2, Y2O3, CeO2, ZrO2, TiO2, La2O3, Cr2O3, and Al2O3) in the gas-phase ketonization of VA to 5-nonanone in the 350–450 °C range. The screening reveals a correlation between the metal oxides lattice energy and their catalytic activity for valeric acid ketonization. ZrO2, TiO2, and La2O3, characterized by high lattice energy, demonstrate the highest catalytic activity, whereas Y2O3, SnO2, and SiO2, showing low lattice energy, are barely active. However, exceptions to this trend were observed: Cr2O3 and Al2O3 displayed poor catalytic performance despite their elevated lattice energy. The comprehensive characterization of the catalysts, encompassing XRD, N2-physisorption, NH3-TPD, and CO2-TPD analyses, has unveiled the crucial role of important parameters including acid–base properties in addition to lattice energy. Only oxides showing amphoteric properties can catalyze the reaction effectively. Interestingly, low-lattice energy and amphoteric oxides such as SnO2 (showing poor performance) become significantly active at higher temperature (500 °C). Analysis of by-products by online GCMS and spent catalyst characterization indicated that in this case the ketonization mechanism changed from the so-called surface mechanism to the so-called bulk mechanism.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 4","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalytic activity test indicates that F-Co3O4 catalyst exhibits better activity with 100% N2O conversion at a reaction temperature of 380 °C, which is 80 °C lower than that of pure Co3O4. The characterization results show that F is successfully doped into the lattice of Co3O4 and replaces part of O sites, which enlarges the surface area, enhances the surface basicity, and leads to higher basic sites density on the surface of Co3O4. Moreover, F doping promotes the electron donation capacity of Co2+, weakening of Co─O bond and generation of more oxygen vacancies. The synergy of the above factors results in reduction of activation energy over F-Co3O4 catalyst, thus F-Co3O4 catalyst exhibits better catalytic performance than pure Co3O4 for N2O decomposition, even in the existence of O2 or H2O as impurity gas. Meanwhile, F-Co3O4 catalyst also exhibits better stability than pure Co3O4.

This work reports the synthesis of two types of nanostructured CeO2–Nb2O5 catalysts: (i) one-pot hydrothermal synthesis of CeO2–Nb2O5 (CeNb2O5-HTS, HTS stands for hydrothermal synthesis) and (ii) CeO2 impregnation on hydrothermally synthesized Nb2O5 nanorods (CeNb2O5-WI, WI stands for wet-impregnation) to elucidate the role of particle shape and CeO2 addition in the structure–activity efficacy of Nb2O5 nanocatalyst for the selective oxidative C–N coupling of benzyl alcohol with aniline to produce N-benzylideneaniline (NBA). The characterization studies showed nanorod morphology of Nb2O5 and high dispersion of CeO2 on Nb2O5 nanorods in the CeNb2O5-WI catalyst with strong acidic sites and more oxygen vacancies. Consequently, a significantly enhanced catalytic activity was achieved with CeNb2O5-WI nanocatalyst in the coupling of benzyl alcohol and aniline with 96% yield to NBA, whereas 62% conversion of aniline with 92% selectivity to NBA was obtained with pure Nb2O5 nanorods. In contrast, the CeNb2O5-HTS catalyst gave 37% conversion of aniline only. The versatile efficiency of the CeNb2O5-WI nanocatalyst is showcased by synthesizing various functional NBA products. The CeNb2O5-WI catalyst can be recycled 4 times without much variation in NBA selectivity by achieving reasonably good conversion of aniline.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 4","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies emphasize the sulfur-resistant properties of catalysts in the hydrogenation of industrial feedstocks, but the direct hydrogenation of sulfur-containing compounds has received limited attention. In this concept, recent advances in the hydrogenation of sulfur-containing compounds were reviewed, including the strategies to improve the resistance of supported metal catalysts to sulfur poisoning.

Since transient operation of FTS reactors might be necessary and even be beneficial, transient kinetics for a rational catalyst and reactor design are essential. In order to advance the development of such transient kinetics, the periodic transient kinetics (PTK) method was applied to the CO hydrogenation on a Co/TiO2 catalyst under FT-like conditions. It was revealed that there are two carbon species of different reactivity, Cα and Cβ, present on the catalyst surface during the reaction. Cα forms fast, within a few seconds, and is highly reactive. Whereas Cβ forms slowly, is accumulating on the surface over a longer time, and imposes an inhibiting effect. The results indicate an important role of the Cβ species to chain growth and the formation of C2+ products. Finally, the transient experimental results were evaluated based on a material balance and the amounts of Cα and Cβ present on the catalyst surface during the reaction were determined.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 4","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202401617","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HEMFC prepared with MnO2 NTM cathode achieves a peak power density of 425 mW cm−2, surpassing the performance of the HEMFC prepared using the traditional powder catalyst spraying method by four times. High-frequency resistance and limiting current tests indicate that the MnO2 NTM reduces ohmic resistance and improves mass transfer, thereby enhancing the HEMFC performance.
