Photocatalytic Overall Water Splitting Promoted by Two Different Cocatalysts for Hydrogen and Oxygen Evolution under Visible Light

In harmony: Nanoparticles of Mn3O4 and core/shell-structured Rh/Cr2O3 as cocatalysts on the surface of a solid solution of GaN and ZnO as catalyst promote O2 and H2 evolution, respectively, under visible light (λ>420 nm), thereby achieving enhanced water-splitting activity compared to analogues modified with either Mn3O4 or Rh/Cr2O3.
