Electrochemical reduction reactions, as cathodic processes in many energy-related devices, significantly impact the overall efficiency determined mainly by performance of electrocatalysts. Metal-organic frameworks (MOFs) derived carbon-supported metal materials have become one star electrocatalysts due to their tunable structure and composition through ligand design screening. However, for different electroreduction required active species vary phase component, electronic state, catalytic center configuration, hence requiring effective customization. From this perspective, review comprehensively analyzes structural principles, loading strategies, practical performance, complex mechanisms, thereby providing insights guidance future rational such catalysts.

Abstract Semihydrogenation is a crucial industrial process. Noble metals such as Pd have been extensively studied in semihydrogenation reactions, owing to their unique catalytic activity toward hydrogen activation. However, the overhydrogenation of alkenes alkanes often happens due rather strong adsorption on active phases. Herein, we demonstrate that incorporation phases single‐atom sites perovskite lattices SrTiO 3 can greatly alternate electronic structure and coordination environment facilitate desorption than further hydrogenation. Furthermore, incorporated be well stabilized without sintering by host–guest interaction with during activation H species hydrogenation reactions. As result, (Pd‐SrTiO ) exhibits an excellent time‐independent selectivity (>99.9 %) robust durability for photocatalytic phenylacetylene styrene.
