Synthesis of MoS/MoO nano-heterojunction towards enhanced photocatalytic activity under LED light irradiation oxidation sintering.

The MoS/MoO nano-heterojunction photocatalyst was synthesized the 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/MoO nano-heterojunction (MS-400) exhibited significantly better photocatalytic activity toward Rhodamine B degradation (0.42634 h) than monomer MoS (∼8.0-folds) and MoO (∼25.6-folds). This is mainly attributed to the MoS/MoO 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 microstructures.
