Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Cu‐Doped Amorphous High‐Entropy Hydroxides Activating Electrochemical Reconstruction: Triggering LOM and Chloride Repellency for Enhanced Water and Seawater Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Copper‐doped amorphous high‐entropy hydroxide (CuNiCoFeCrOH) is constructed via one‐step electrodeposition. Cu doping promotes electrochemical reconstruction by accelerating Cr leaching and re‐adsorption, triggering LOM and chloride repellency for efficient water and seawater oxidation.
