The surface property of a photocatalyst, including acid sites and oxygen vacancies, plays pivotal role in photocatalytic organic synthesis reactions. Benzoin isopropyl ether (BIE) is usually produced via polycondensation benzaldehyde catalyzed with highly toxic cyanide. Here, we report green approach for the selective BIE over WO3 driven by green-light-emitting diode. improved activity can be attributed to synergy vacancies (VOs) N-doped nanobelts. results revealed that reactant molecules were predominantly adsorbed activated on (VOSs) Brønsted promoted etherification reaction; introduction VOs nitrogen altered band structure electronic properties, resulting activity. Our work provides an efficient organics photocatalysts finely tuned properties structures defect doping engineering.
