Selective loading of platinum or silver cocatalyst onto a hydrogen-evolution photocatalyst in a silver-mediated all solid-state Z-scheme system for enhanced overall water splitting

We selectively loaded a hydrogen (H(2))-evolution cocatalyst, either platinum (Pt) or silver (Ag), onto a H(2)-evolution photocatalyst, zinc rhodium oxide (ZnRh(2)O(4)), in a Ag-inserted ZnRh(2)O(4) and bismuth vanadium oxide (Bi(4)V(2)O(11)) hetero-junction photocatalyst (ZnRh(2)O(4)/Ag/Bi(4)V(2)O(...

Descripción
Sumario:We selectively loaded a hydrogen (H(2))-evolution cocatalyst, either platinum (Pt) or silver (Ag), onto a H(2)-evolution photocatalyst, zinc rhodium oxide (ZnRh(2)O(4)), in a Ag-inserted ZnRh(2)O(4) and bismuth vanadium oxide (Bi(4)V(2)O(11)) hetero-junction photocatalyst (ZnRh(2)O(4)/Ag/Bi(4)V(2)O(11)) by a photo-deposition method. The selective loading of Pt or Ag was achieved by taking advantage of the band-gap difference between ZnRh(2)O(4) (1.2 eV) and Bi(4)V(2)O(11) (1.7 eV) and increased the overall water-splitting activity of the photocatalyst.
