Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

Advanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...
