Abstract
ABSTRACT Recently, noble metal nanoparticles (e.g., Au, Ag, and Pt) have gained widespread attention as promising co‐catalysts with potential applications in reducing O 2 into H 2 O 2 . However, the O 2 ‐to‐H 2 O 2 conversion efficiency is generally limited due to their inherent weak adsorption capability toward O 2 . Herein, we have designed p‐type Ag/CdZnS Schottky junctions to address this issue. It is demonstrated that Ag nanoparticles are regulated to be electron‐deficient through diffusion of thermoelectrons (thermally excited at any temperature) from Ag to CdZnS, thereby enhancing O 2 adsorption on the Ag active sites. On the other hand, the photoelectrons generated in CdZnS during the photocatalysis…
