Defects Healing of the ZnO Surface by Filling with Au Atom Catalysts for Efficient Photocatalytic H2 Production (Small 4/2024)

Photocatalytic Hydrogen Production In article number 2304393, Jihoon Choi, Yeonho Kim, and co-workers show that artificially generated surface defects of ZnO heal by filling of Au atoms through the in-situ photoreduction process. The advantageous interface junction between the Au atom and ZnO effectively separates photogenerated electron-hole pairs resulting in remarkable photocatalytic hydrogen production.
