Enhanced photocatalytic performance of molybdenum disulfide-copper oxide nanoparticles photoanodes

In this paper, the molybdenum disulfide (MoS 2 )/copper oxide (CuO) heterostructure is introduced in a very simple way for photoelectrochemical application. MoS 2 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 MoS 2 multilayers and produces a significant photocurrent compared to the individual MoS 2 electrode. Such a proposed structure demonstrates a high potential for photoelectrochemical applications.
