Excessive hole-accumulation-induced photocorrosion is considered a key factor that limits the activity of photoelectrochemical water splitting reaction. In this study, heterogeneous catalyst was prepared by simple impregnation method, i.e., modification different ratios heterometallic oxyhydroxides (FexCo1-xOOH) on in situ photoreduction-treated BiVO4 (Bi-BVO). This work demonstrates for first time adjusting FeCo ratio can greatly enhance separation, transport, and directional control electron-hole pairs, thus inhibiting photocorrosion. The Bi-BVO/Fe0.7Co0.3OOH composite exhibited photocurrent density 0.243 mA cm-2 at 1.23 VRHE (4.5 times pure under 1.5 G AM illumination) sacrificial agent-free Na2SO4 electrolyte. After 20 h continuous illumination, optimized samples showed negligible attenuation (7.2%). strong stability light conditions be attributed to Fe Co acting as hole shuttling mediators, which efficiently match generation rate Bi-BVO transport surface active sites. Furthermore, formation Co-O-V bonds passivation states, immobilize V5+ lattice, further inhibit bimetallic oxyhydroxide strategy provides valuable insights into mitigating offers an optimization approach splitting.
