Abstract Photoelectrochemical solar to hydrogen production is a promising way achieve carbon neutrality, but severe charge recombination in photoanodes limits the conversion efficiency. Herein, Au nanoparticles and Co(OH) x co‐sensitized bismuth vanadate (BiVO 4 ) construct AuCo(OH) /BiVO photoanode for significantly enhancing performance of photoelectrochemical water splitting. This process improves bulk carrier separation efficiency, surface kinetics oxidation, electron density BiVO through plasmon resonance (SPR) oxygen evolution catalysts effect. Additionally, enhancement *O *OOH generation accelerate reaction kinetics. Consequently, constructed demonstrates an excellent photocurrent 6.2 mA cm −2 at 1.23 V versus reversible electrode stable continuous output within 42 h. work contributes developing high‐efficiency high‐stability H 2 SPR effect catalysts.

The photoelectrochemical (PEC) conversion of organic small molecules offers a dual benefit synthesizing value-added chemicals and concurrently producing hydrogen (H2). Ethylene glycol, with its hydroxyl groups, stands out as versatile substrate capable yielding various C1 C2 chemicals. In this study, we demonstrate that pH modulation markedly enhances the photocurrent BiVO4 photoanodes, thus facilitating efficient oxidation ethylene glycol while simultaneously generating H2. Our findings reveal in = 1 solution, density at 1.23 V vs. RHE can attain an impressive 7.1 mA cm−2, significantly surpassing outputs neutral highly alkaline environments. increase is attributed to augmented adsorption on under acidic conditions, which turn elevates activity reaction, culminating maximal production formic acid. This investigation sheds light pivotal role electrolyte PEC process underscores potential strategy for biomass valorization into products alongside H2 fuel generation.
