In this paper, the molybdenum disulfide (MoS2)/copper oxide (CuO) heterostructure is introduced in a very simple way for photoelectrochemical application. MoS2 multilayers were prepared by sonication method and decorated with copper oxide nanoparticles through its thin film deposition layer and heating in argon atmosphere. SEM, TEM, AFM, absorption and Raman analyses were employed to characterize the nanostructures. The results show that the presence of copper oxide nanoparticles reduces the recombination rate of photogenerated electron-holes in MoS2 multilayers and produces a significant photocurrent compared to the individual MoS2 electrode. Such a proposed structure demonstrates a high potential for photoelectrochemical applications.
