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.

To address the problem of suboptimal performance in deep eutectic solvents displayed by traditional TiO2 photoelectrodes and Cu2O that have undergone simplistic modifications result a mismatch with battery discharge capacity, method combining hydrothermal dip-coating techniques was developed to create Fe2O3-CuO heterojunction structure on FTO surface. Then, impact solar flow batteries investigate this study. The experimental findings reveal formation effectively mitigates recombination rate photogenerated carriers within photoelectrode. Furthermore, meticulously adjusting CuO loading, harmonious balance between charging discharging currents achieved, thereby enhancing overall redox batteries. In comparison standalone Fe2O3 photoelectrodes, innovative approach significantly broadens spectrum sunlight utilization. Notably, fabricated Fe2O3/CuO-2 photoelectrode demonstrates remarkable photocharging performance, far surpassing both commercial photoelectrodes. Specifically, boosts an average current density 598.68 μA∙cm−2, its being 2.74 5.15 larger, respectively, than
