Photoelectrochemical (PEC) water splitting with zero carbon emissions is a promising technology to solve the global issues of energy shortage and environmental pollution. However, the current development of PEC systems is facing a bottleneck of low solar‐to‐hydrogen (STH) efficiency (<10%), which cannot meet the demand of large‐scale H2 production. The development of low‐cost, highly active, and stable photoanode materials is crucial for high STH efficiency of PEC water splitting. The recent development of BiVO4 as photoanode materials for PEC water splitting has been a great success, and ABO4‐type ternary metal oxides with a similar structure to BiVO4 have high development potential as efficient photoanodes for high‐performance PEC water splitting. The design and development of ABO4 photoanodes for PEC water splitting are critically reviewed with special emphasis on the modification strategies and performance improvement mechanisms of each semiconductor. The comprehensive analysis in this review provides guidelines and insights for the exploration of new high‐efficiency photoanodes for solar fuel production.

“…In parallel with the V-site doping with hexavalent ions, doping Bi sites with trivalent elements is found to be a feasible strategy to improve the PEC performance of BVO photoanodes. − Previous reports have explored the use of In 3+ , Gd 3+ , or Ce 3+ ions in Bi sites for BVO photoanodes, which suggests that such dopants could modify the surface catalytic activity and so enhance their PEC performance. , However, these doped BVO electrodes are usually accompanied by an apparent structural distortion and morphological evolution, which makes the elucidation of the doping mechanism highly convoluted. Besides, it is not clear how these dopants affect the transport behavior as they are found to be correlated to structural distortions and native defect formation, ,, representing a critical direction for optimizing the transport behavior in BVO.

Unraveling the Site-Selective Doping Mechanism in Single-Crystalline BiVO₄ Thin Films for Photoelectrochemical Water Splitting

Doping with extrinsic elements in bismuth vanadate (BiVO4, BVO) has been widely exploited for boosting photoelectrochemical (PEC) water splitting. However, changes in the carrier transport behavior of doping, in particular for the Bi-site doping in BVO, are still not well understood. Here, we explore the im pact of site-selective doping on structural variation and electron transport in BVO as well as its implication for designing photoanodes with improved photoelectrochemical (PEC) performance. Two types of single-crystalline doped BVO films, with the V site substituted with Mo (MoV) ions or the Bi site substituted with Gd ions (GdBi), are prepared by pulsed-laser deposition. Compared to pristine BVO, both types of doped photoanodes are found to require thinner films for delivering larger photocurrents, but the underlying doping mechanism appears to be different. Combined with temperature-dependent Raman characterization, X-ray photoelectron microscopy, and solid-state electron transport measurements, it is suggested that GdBi doping facilitates carrier transport by introducing structural distortion and a gentle increase in the oxygen vacancy concentration. This is in contrast to MoV doping, which substantially enhances the donor density and facilitates carrier hopping. This work provides a perspective on understanding the impact of site-selective doping on BVO photoanodes for efficient PEC water splitting.
