Abstract As is well known, there are problems such as low utilization rate of photogenerated holes and resource consumption sacrificial agent in solar‐driven photocatalytic water splitting to hydrogen technology. Herein, WC quantum dots decorated defective ZnIn 2 S 4 nanosheets (DZIS/WCQDs) dual‐functional photocatalysts fabricated. Its unique Schottky junctions photothermal effect significantly promote the separation transport efficiency carriers, achieving synergistic enhancement coupled with selective oxidation benzyl alcohol (BA). Moreover, can slowly induce decomposition H O produce ·OH, concentration ·OH continuously generated situ directly rapidly attack αC─H bond BA improve benzaldehyde (BAD) conversion selectivity. Consequently, DZIS/WCQDs composites exhibit a surprising selectivity 85.34% 96.53% for BAD, outstanding BAD evolution rates 12.58 10.53 mmol g −1 h without co‐catalyst. Notably, combining production products, optimal catalyst material at present. This work opens up green carbon free effective path solve high cost production.
