Abstract：xploring efficient and cost-effective co-catalysts to improve the performance of photocatalytic hydrogen production is crucial for advancing solar energy utilization technology. In this work, two-dimensional Ti3C2Tx nanosheets were successfully prepared through a selective etching method followed by a liquid-phase exfoliation process with Ti3AlC2 as the precursor material. Based on this as-synthesized material, we further built a novel heterojunction photocatalyst by decorating Ti3C2Tx with Cd0.8Zn0.2S nanoparticles using a conventional hydrothermal method. Taking advantage of the good electronic conductivity of Ti3C2Tx nanosheets, the resulting Cd0.8Zn0.2S/Ti3C2Tx nanomaterial exhibited superior separation and migration abilities of photoexcited electron-hole pairs, leading to a notable increase in hydrogen evolution activity. Under visible light irradiation, the Cd0.8Zn0.2S/Ti3C2Tx photocatalyst displayed a remarkable hydrogen evolution rate of 1 954.2 μmol/(g·h), which was 4.2 times higher than that of pristine Cd0.8Zn0.2S under the same conditions.
