Synthesis of ZnO/MoS2 nanocomposite for photodegradation of Methylene blue

Abstract An effective way to boost ZnO's photocatalytic activity is to decorate it with MoS2 nanosheets, a transition metal dichalcogenide with a narrow band gap. Fewer studies, nevertheless, demonstrate how multilayers of MoS2 nanosheets affect ZnO/MoS2 photocatalytic activity. ZnO nanorods were adorned in this study with low-layer and multilayer MoS2 nanosheets (about 11 and 3 atomic layers), which were annealed for 4 and 8 hours, respectively. The breakdown of methyl blue was subsequently explained using this kind of heterostructure. Our findings demonstrate that the ZnO/MoS2 photocatalytic efficiency is not only less than that of pure ZnO but also declines by 11% as the length and number of MoS2 nanosheet layers increase. The reduction in adsorption capacity could be the cause of this effect. of the ZnO/MoS2 system's water molecules as the contact angle rises from 17o–23o to 73o–76o. Because the planar surface of the 2H-MoS2 phase is hydrophobic, or an inactive catalytic site, there is an increased contact angle for ZnO/MoS2.
