Electrocatalytic water splitting driven by sustainable energy is a clean and promising water‐chemical fuel conversion technology for the production of high‐purity green hydrogen. However, the sluggish kinetics of anodic oxygen evolution reaction (OER) pose challenges for large‐scale hydrogen production, limiting its efficiency and safety. Recently, the anodic OER has been replaced by a nucleophilic...
Integrating high‐entropy philosophy and nanocrystal‐specific orientation into a single catalyst represents a promising strategy in development of high‐performance catalysts. Nonetheless, shape‐controlled synthesis of high‐entropy alloy (HEA) nanocrystals is challenging owing to the distinct redox potentials and growth dynamics of metal elements. Herein, a one‐pot co‐reduction method is developed to...
Electrochemical nitrogen reduction powered by renewable electricity is a promising strategy to produce ammonia. However, the lack of efficient yet cheap electrocatalysts remains the biggest challenge. Herein, hybrid Cu2O‐CeO2‐C nanorods are prepared on copper mesh through a metal‐organic framework template route. The Cu‐loaded Ce‐MOF is thermally converted to Cu2O‐CeO2 heterojunctions with interfacial...
The reduction of the overall electrolysis potential to produce hydrogen is a critical target for fabricating applicable hydrogen evolution cells. Sandwich‐structured Fe3O4/Au/CoFe‐LDH is synthesized via a spontaneous galvanic displacement reaction. A series of structural characterizations indicate the successful synthesis of sandwich‐structured Fe3O4/Au/CoFe‐LDH electrocatalyst. The trace amount of...
