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 ...

Constructed Red Phosphorus/BiVO4 S‐Scheme Heterojunction for Efficient Photocatalytic Overall Water Splitting

EcoEnergy, EarlyView.
An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.

Breaking the Activity–Stability Scaling in RuO2 via Single‐ and Dual‐Doping Strategies

EcoEnergy, EarlyView.
Single and dual heteroatom doping redefines RuO2 for acidic oxygen evolution by synergistically tuning the electronic structure, lattice stability, and reaction pathways. Although single dopants optimize specific catalytic properties, dual dopants overcome the activity–stability trade‐off through cooperative electronic and geometric regulation ...
