摘　　要：针对现阶段过渡金属硫化物光催化制氢的困难,研究通过引入非晶态磷化钨调节全硫代铟酸锌的带隙结构,成功制备了一种新型的过渡金属硫化物异质结。实验结果表明,这种双金属硫化物复合材料在光催化析氢反应中表现出了显著的性能提升,其在5 h的光催化析氢活性达到了7068 mol/g,在10 h的制氢效率则达到了95.6%。由此可知,非晶态磷化钨的引入能够增强全硫代铟酸锌的光吸收强度,促进光生载流子的分离和电子转移速率,进而提高材料的整体光催化活性。Aiming at the difficulties of transition metal sulfide photocatalytic hydrogen production at the present stage,the study successfully prepared a novel transition metal sulfide heterojunction by introducing amorphous tungsten phosphide to modulate the bandgap structure of zinc perthiolate.The experimental results show that this bimetallic sulfide composite exhibits significant performance enhancement in the photocatalytic hydrogen precipitation reaction,with its photocatalytic hydrogen precipitation activity reaching 7068 mol/g at 5 h and hydrogen production efficiency reaching 95.6% at 10 h.The results show that this bimetallic sulfide heterojunction can be used for the photocatalytic hydrogen precipitation reaction.It can be seen that the introduction of amorphous tungsten phosphide can enhance the light absorption intensity of zinc all-thiored indurate,promote the separation of photogenerated carriers and electron transfer rate,and then improve the overall photocatalytic activity of the material.
