Sulfur-doped g-C3N4/g-C3N4 isotype step-scheme heterojunction for photocatalytic H2 evolution
文献摘要：
The rational fabrication of an efficient heterojunction is critical to the enhancement of photocatalytic hydrogen(H2)evolution performance.Herein,a new-fashioned graphitic-carbon nitride(g-C3N4)based isotype step-scheme(S-scheme)heterojunction composed of sulfur-doped and sulfur-free active sites is developed by liquid sulfur-mediation of exfoliated g-C3N4.Particularly,the liquid sulfur not only con-tributes to the full contact between sulfur species and exfoliated g-C3N4,but also creates sulfur-doping and abundant pores,since self-gas foaming effect of sulfur vapor.Moreover,the S-doped and S-free active sites located in the structural unit of C3N4 jointly construct a typical sulfur-doped g-C3N4/g-C3N4 isotype step-scheme heterojunction,which endows highly efficient photocatalytic reaction process.Therefore,the optimal sample possesses remarkable photocatalytic H2 evolution activity(5548.1 μmol g-1 h-1)and ro-bust durability.Most importantly,the investigation will open up a new path for the exploration of other carbon-based isotype S-scheme heterojunctions.
