Synthesis of novel 1t/2h-mos2 from moo3 nanowires with enhanced photocatalytic performance

Abstract

Metallic 1T-phase MoS2 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-MoS2 . Herein, 1T/2H-MoS2 (N) (N: MoO3 nanowires were used to prepare 1T/2H-MoS2 ) was synthesized by using molybdenum trioxide (MoO3 ) 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-MoS2 (N), which was 2.8 and 1.3 times higher than those on 1T/2H-MoS2 (P) (P: commercial MoO3 powder was used to prepare 1T/2H-MoS2 ) and 2H-MoS2, respectively. The active component responsible for the photodegradation was detected and a reaction mechanism is proposed.
