Summary: As an important reaction for electrochemical water splitting, the hydrogen evolution reaction (HER) suffers from slow kinetics and the need for high efficiency non-platinum-based electrocatalysts. Mo-based catalysts, such as Mo2C, MoO2, MoP, MoS2, and MoNx, have emerged as promising alternatives to Pt/C due to their similar electronic structure with Pt and abundant reserve of Mo. Metal organic frameworks (MOFs) have adjustable topology, porosity, and nanostructure, making them useful precursors for nano-electrocatalysts. In this review, the progress of Mo-MOFs-derived electrocatalysts for HER is summarized, including the preparation method, structures, and catalytic performance of the derived catalysts such as Mo2C, MoO2, MoP, MoS2, and MoNx. Strategies to improve catalytic performance, such as heteroatoms doping, constructing heterogeneous structures, and compositing with noble metals, are discussed. Opportunities and challenges in this area are proposed to guide the design and development of Mo-based MOF-derived electrocatalysts.

Summary: Metal-organic frameworks (MOFs) have shown promising potential as electrode materials for the oxygen evolution reaction (OER). This study revealed that MOFs with tetrahedral Co sites exhibit continuous active sites in the OER, while those with octahedral sites are inert. Co-N coordination is more favorable for electrochemical activation than Co-O coordination, leading to the gradual increase in activity of the MOF in the OER process.

Summary: The development of water electrolysis devices is crucial for the sustainable production of green hydrogen fuel. The chemical functionalization of organic linkers in MOFs enhances catalytic activity by providing Lewis acidity or basicity. The presence of surface amino functions slightly improved HER activity of cobalt MOFs in terms of overpotential and Tafel slope. Co-2 showed better stability and high Faradaic efficiency due to morphological features, mesoporosity, and the presence of basic surface functionalities.

Summary: The direct conversion of methane and carbon dioxide into acetic acid is a promising approach to mitigate the greenhouse gas effect and reduce reliance on traditional fossil fuels. In this study, the catalytic transformation of methane and carbon dioxide to acetic acid over a zinc single-atom catalyst supported on In2O3 nanomaterial with surface oxygen vacancy was investigated. The results indicate that the zinc single atom facilitates the dissociation of methane and stabilization of methyl species, while the surface oxygen vacancy promotes the adsorption and activation of carbon dioxide. The synergistic effect of the zinc single atom and surface oxygen vacancy enables the facile coupling reaction between methyl and carbon dioxide, leading to the formation of a Zn-C-C moiety. The subsequently formed acetate species interacts strongly with the zinc single atom and undergoes protonation to form acetic acid. The desorption of acetic acid is identified as the rate-determining step. These findings provide insights into the reaction mechanism of producing acetic acid from methane and carbon dioxide over the zinc single-atom catalyst and offer valuable guidance for the design of efficient catalysts for methane and carbon dioxide conversion.
