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

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 m...

Zusammenfassung: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.
