Title : Role and significance of molybdenum disulfide (MoS2 ) as a cocatalyst for photocatalytic hydrogen production


Modern advancement in design of the efficient visible driven photocatalyst for solar-to-hydrogen generation has been expanded much consideration due to fossil fuels crisis, which convert and store solar energy into chemical fuels. In view point of economic and large-scale application, semiconductor photocatalyst with high stability and efficiency should be required. However, a numerous number of materials have been discovered, challenges still remain for the commercialization. Among the enormous number of materials, layered structured transition metal dichalcogenides (TMDs) based photocatalyst have been shown attractive performance in photocatalytic process owing to their suitable narrow bandgaps, high absorption capacity and fast carrier transport properties. This review to be covered the physicochemical features and recent advancements of various layered structured TMDs based photocatalysts, especially MoS2 and various approaches to improve the photocatalytic reaction and stability by coupling active carbon materials including graphene, carbon nanotubes (CNTs), active carbon, precious metals and other metal oxides, etc. We rely on this review can reveal some insights of fundamental concepts of role of active chemical species during the solar-to hydrogen conversion processes and their influences in enhanced performance on PEC water splitting.
