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 pH=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.

Abstract Dihydroxyacetone is the most desired product in glycerol oxidation reaction because of its highest added value and large market demand among all possible products. However, selectively oxidative secondary hydroxyl groups for highly efficient dihydroxyacetone production still poses a challenge. In this study, we engineer surface BiVO 4 by introducing bismuth-rich domains oxygen vacancies (Bi-rich 4-x ) to systematically modulate adsorption enhance photo-induced charge separation photoelectrochemical into conversion. As result, Bi-rich increases photocurrent density from 1.42 4.26 mA cm −2 at 1.23 V vs. reversible hydrogen electrode under AM 1.5 G illumination, as well selectivity 54.0% 80.3%, finally achieving rate 361.9 mmol m h −1 that outperforms reported values. The atom customization opens way regulate solar-driven organic transformation pathway toward carbon chain-balanced product.

Organic electrosynthesis in aqueous media is presently hampered by the poor solubility of many organic reactants and thus low purity liquid products electrolytes. Using electrooxidation benzyl alcohol (BA) as a model reaction, we present "sandwich-type" organic-solid-water (OSW) system, consisting BA phase, KOH electrolyte, porous anodes with Janus-like superwettability. The system allows independent diffusion molecules from phase to electrocatalytic active sites, enabling efficient high-concentration benzaldehyde (97% Faradaic efficiency at ~180 mA cm
