Abstract The semi‐hydrogenation of acetylene in ethylene‐rich gas streams is a high‐priority industrial chemical reaction for producing polymer‐grade ethylene. Traditional thermocatalytic routes reduction to ethylene, despite progress, still require high temperatures and H 2 consumption, possess relatively low selectivity, use noble metal catalyst. Light‐powered strategies are starting emerge, given that they have the potential directly abundant sustainable solar irradiation, but ineffective. Here an efficient, >99.9% selective, visible‐light powered, catalytic conversion ethylene reported. catalyst homogeneous molecular cobaloxime operates tandem with photosensitizer at room temperature bypasses non‐environmentally friendly flammable feed. proceeds through cobalt‐hydride intermediate ≈100% under competitive (ethylene co‐feed) conditions after only 50 min, no evolution or over‐hydrogenation ethane. further incorporated as linker metal–organic framework; result heterogeneous can be recycled up six times remains catalytically active 48 h, before significant loss performance observed.

Abstract Metal–organic frameworks (MOFs) have emerged as promising materials in the realm of electrocatalysis due to their high surface area, tunable porosity, and versatile chemical functionality. However, practical application has been hampered by inherent limitations such low electrical conductivity a limited number active metal sites. Researchers addressed these challenges through various strategies, including enhancing incorporating conductive nanoparticles, modifying structure composition MOFs replacing nodes functionalizing linkers, preparing catalysts thermal processes decarburization conversion into oxides, phosphides (MPs), sulfides (MSs). This review provided comprehensive summary strategies that were employed enhance electroactivity for improved electrocatalytic performance recent years. It also explored future directions potential innovations design synthesis MOF‐based electrocatalysts, offering valuable insights advancing sustainable energy technologies.
