Abstract Photocatalytic hydrogen production through water splitting represents a promising strategy to store solar energy as chemical energy. Current photocatalysts primarily focus on traditional semiconductor materials, such metal oxides, sulfides, nitrides, g‐C 3 N 4 , etc. However, these materials often suffer from large bandgap and fast charge recombination, which limit sunlight utilization result in unsatisfactory photon conversion efficiency. Here, novel 3D/2D graphene/MXene (3DGraphene/MXene) photocatalyst without participant is designed, an enhanced hot/free electron catalytic mechanism for photocatalytic evolution proposed. The electrons, ejected out 3DGraphene based Auger‐like light induced emission by the cocatalyst MXene Ti C 2 T x exhibit exceptional activity under wide spectrum range ultraviolet visible light. optimized 3DGraphene/MXene composite catalyst achieves average rate of 1.4 mmol h −1 g cat . Furthermore, consistent with proposed emitting mechanism, photocurrent rises increasing intensity same frequency range. These results indicate that using hot generated graphene other 2D might be effective enhancing splitting.

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.
