Multiple ion doping in BiVO4 as an effective strategy of enhancing photoelectrochemical water splitting: A review

Bismuth vanadate (BiVO4) is one of the extensively studied semiconductors in solar water splitting reactions. Due to its inherent properties, much of the utilization of BiVO4 in water splitting is focused on the modified form rather than in native or pure form. Because the pure BiVO4 suffers from nu...

Due to its inherent properties, much of the utilization of BiVO4 in water splitting is focused on the modified form rather than in native or pure form.

Recently, the doping strategy in BiVO4 has shifted beyond the single element doping to the co-doping strategy (involving multiple dopants) to further boost the water splitting efficiency that provides extended advantages. In this review, the advancements of co-doping strategies implemented in BiVO4 and their influence on structural, optical, chemical, band edge properties, and stability were summarized.
