We selectively loaded a hydrogen (H)-evolution cocatalyst, either platinum (Pt) or silver (Ag), onto a H-evolution photocatalyst, zinc rhodium oxide (ZnRhO), in a Ag-inserted ZnRhO and bismuth vanadium oxide (BiVO) hetero-junction photocatalyst (ZnRhO/Ag/BiVO) by a photo-deposition method. The selective loading of Pt or Ag was achieved by taking advantage of the band-gap difference between ZnRhO (1.2 eV) and BiVO (1.7 eV) and increased the overall water-splitting activity of the photocatalyst.
我们通过光沉积法，将析氢助催化剂铂（Pt）或银（Ag）选择性地负载到析氢光催化剂氧化锌铑（ZnRhO）上，该析氢光催化剂存在于银插入的ZnRhO和钒酸铋（BiVO）异质结光催化剂（ZnRhO/Ag/BiVO）中。利用ZnRhO（1.2电子伏特）和BiVO（1.7电子伏特）之间的带隙差异实现了Pt或Ag的选择性负载，并提高了光催化剂的整体水分解活性。
