主 题：ZnIn2S4 Nanosheets Sulfur vacancies Photocatalytic hydrogen production
摘 要：The remarkable properties exhibited by two-dimensional(2D) photocatalytic materials,differing from bulk materials,have captivated significant *** this study,a hexagonal-phase ZnIn2S4were synthesized using thiosulfate,thioacetamide,and L-cysteine as sulfur sources(denoted as ZIS-A,ZIS-B and ZIS-C),*** synthesized ZnIn2S4 exhibited varying morphologies and photocatalytic properties,which were characterized through XRD,SEM,TEM,EPR,XPS and so *** results confirmed that ZIS-B with 2D nanosheets structures exhibited superior photocatalytic properties compared with that of the flower-like spheres and block *** hydrogen evolution rate of the ZIS-B is 3653 μmol g-1h-1,which is 3.1 times than that of the other *** improvement was attributable to that the ZIS-B have 2D nanosheets structures and sulfur ***,the 2D nanosheets structure endowed ZnIn2S4with a larger surface area and abundant reactive sites for efficient evolution ***,the presence of sulfur vacancies served as active sites,facilitating carrier transport and ultimately promoting the rate of photocatalytic hydrogen *** results present a novel method for optimizing 2D ZnIn2S4photocatalyst to improve the photocatalytic hydrogen evolution.
