Synthesis of Novel 1T/2H-MoS(2) from MoO(3) Nanowires with Enhanced Photocatalytic Performance

Metallic 1T-phase MoS(2) 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(2). Herein, 1T/2H-MoS(2)(N) (N: MoO(3) nanowires were used to prepare 1T/2H-MoS(2)) was synt...

Sumario:Metallic 1T-phase MoS(2) 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(2). Herein, 1T/2H-MoS(2)(N) (N: MoO(3) nanowires were used to prepare 1T/2H-MoS(2)) was synthesized by using molybdenum trioxide (MoO(3)) 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(2)(N), which was 2.8 and 1.3 times higher than those on 1T/2H-MoS(2)(P) (P: commercial MoO(3) powder was used to prepare 1T/2H-MoS(2)) and 2H-MoS(2), respectively. The active component responsible for the photodegradation was detected and a reaction mechanism is proposed.
