Synthesis of Novel 1T/2H-MoS2 from MoO3 Nanowires with Enhanced Photocatalytic Performance

摘要

Metallic 1T-phase MoS is a newly emerging and attractive catalyst since it has more available active sites and high carrier mobility in comparison with its widely used counterpart of semiconducting 2H-MoS . Herein, 1T/2H-MoS (N) (N: MoO nanowires were used to prepare 1T/2H-MoS ) was synthesized by using molybdenum trioxide (MoO ) nanowires as the starting material and applied in the photodegradation of antibiotic residue in water. Enhanced photocatalytic performance was observed on the obtained 1T/2H-MoS (N), which was 2.8 and 1.3 times higher than those on 1T/2H-MoS (P) (P: commercial MoO powder was used to prepare 1T/2H-MoS ) and 2H-MoS , respectively. The active component responsible for the photodegradation was detected and a reaction mechanism is proposed.
