Sumario:Flower-like MoS(2) nanoparticles (NPs) consist of ultra-thin MoS(2) nanosheets are synthesized via a facile one-pot hydrothermal method. The MoS(2)/ZnO p-n heterostructure is formed by coating n-type ZnO on the surface of flower-like MoS(2) NPs through the seed-mediate route and post-annealing treatment. The effects for the dye removal and photocatalytic performances after ZnO coating are systematically investigated. The results demonstrated that the coating of ZnO nanoparticles has a positive promotion to the photodegrading properties while negative effect on the adsorption capacity of the MoS(2)/ZnO heterostructures. The related mechanisms on the relationship of adsorption capacity and photocatalysis are discussed in detail.
