The coupling of oxygen evolution reaction (OER) catalysts with photoanodes is a promising strategy for enhancing the photoelectrochemical (PEC) performance by passivating photoanode's surface defect states and facilitating charge transfer at photoanode/electrolyte interface. However, serious interface recombination issue caused poor OER coating quality often limits further improvement photoanodes. Herein, rapid Fenton-like method demonstrated to produce ultrathin amorphous Ni:FeOOH in situ-induced vacancies (Vo) improve water oxidation activity stability BiVO4 combined physical characterizations, PEC studies, density functional theory calculations revealed that reductive environment situ produces abundant Vo catalysts, which significantly improves separation efficiency while also offering active sites reduced energy barrier OER. As result, Ni:FeOOH-Vo yielded more than 2-fold increased photocurrent photoanode (from 1.54 4.15 mA cm-2 1.23 VRHE), accompanied high 5 h. This work not only highlights significance but provides new insights into rational design fabrication efficient stable solar water-splitting systems.

The utilization of fossil fuels to meet ever-increasing energy demands is causing a significant threat the Earth's climate and its inhabitants. To address this issue, photoelectrochemical (PEC) water splitting has emerged as promising solution produce oxygen (O2) hydrogen (H2) in cost-effective, environmentally friendly, clean, renewable manner. In study, we present development cost-effective Cu3Se2 S-doped thin films on Fluorine-doped Tin Oxide (FTO) substrates using chemical bath deposition (CBD) process enhance efficiency PEC oxidation oxygen. X-Ray Diffraction (XRD) pattern confirms presence single-phase tetragonal crystal structure with noticeable shift characteristic (2 1 1) reflection towards higher 2θ value, from 38.1° 38.4°, indicating successful doping S films. further validate lattice, X-ray photoelectron spectroscopy (XPS), dispersive (EDX), Fourier transform infrared (FTIR), Raman Spectroscopy were employed. TEM reveals granular an average particle size 7–8 nm, which consistent crystallite determined by XRD. Furthermore, valence band conduction edge positions are found be 1.56 −0.57 eV, respectively. increased gap Cu3Se2, 1.97 2.15 thus confirming bending upon doping. specific surface areas (SSA) pristine 5.03 111.48 m2g−1, respectively, showing twenty-two-fold increase performance materials was evaluated through chopped chronoamperometry (CA), linear sweep voltammetry (LSV), electrochemical impedance (EIS), Mott-Schottky (M-S) analysis. prepared under optimum conditions, exhibited photocurrent density difference 880 µA cm−2, 6 times greater than for film. results indicate negative slope, implying p-type conductivity, lower flat potential value 0.33 V vs. RHE.
