Abstract The transition metal oxides/sulfides are considered promising catalysts due to their abundant resources, facile synthesis, and reasonable electrocatalytic activity. Herein, a significantly improved intrinsic catalytic activity is achieved for constructing Co‐based nanocrystal (Co‐S@NC) with the coordination of Co─S, Co─S─C, Co─N x ─C. calculational experimental results demonstrate that diversified chemical environment Co‐cations induces 3d orbitals high spin‐state exhibits coexistence Co 2+ fully occupied d π 3+ unpaired electrons in orbitals. diverse occupation contributes an elevated d‐band center ions, which accelerates oxygen reduction reaction evolution kinetics Co‐S@NC nanocrystal. Therefore, Li–O 2 batteries as cathode catalyst exhibit 300 cycles at current density 500 mA g −1 cut‐off capacity 1000 mAh .

In the face of escalating environmental challenges such as fossil fuel dependence and water pollution, innovative solutions are essential for sustainable development. this regard, zeolitic imidazolate frameworks (ZIFs), specifically ZIF-8, act promising photocatalysts remediation renewable energy applications. a subclass metal-organic (MOFs), is renowned its large specific surface area, high porosity, rapid electron transfer ability, abundant functionalities, ease designing, controllable properties, remarkable chemical thermal stability. However, application standalone photocatalyst limited by issues particle aggregation, poor stability, insufficient visible light absorption. By integrating ZIF-8 with various photoactive materials to form composite catalysts, these drawbacks can be mitigated, leading enhanced photocatalytic efficiency. The review discusses synthesis, applications ZIF-8-based in light-driven H2 evolution, H2O2 CO2 reduction, dye drug degradation. It also highlights future research directions developing cost-effective, scalable, environmentally friendly composites industrial potential contribute global cleanup significant, yet further exploration required harness their capabilities thoroughly.

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.
