Abstract
The MoS(2)/MoO(3) nano-heterojunction photocatalyst was synthesized via the in situ oxidation sintering method. The properties of the samples were characterized by XRD, SEM, EDX, TEM, UV-vis, PL, FT-IR, BET and electrochemical techniques. The MoS(2)/MoO(3) nano-heterojunction (MS-400) exhibited significantly better photocatalytic activity toward Rhodamine B degradation (0.42634 h(-1)) than monomer MoS(2) (∼8.0-folds) and MoO(3) (∼25.6-folds). This is mainly attributed to the MoS(2)/MoO(3) heterojunction interface having an appropriate potential gradient that can promote the interface carrier transportation/separation to optimize the carrier efficiency and increase the solar absorption and specific surface areas/active sites via microstructures.
