Abstract
Novel MoS2/Ag2CrO4 composites were successfully fabricated via a simple hydrothermal and in-situ precipitation method and evaluated by the photocatalytic degradation of methyl orange (MO) model organic pollutant under visible light irradiation (λ> 420 nm). The as-obtained MoS2/Ag2CrO4 composites exhibited much higher visible light driven photocatalytic activities towards MO photodegradation than that of pure Ag2CrO4 and MoS2. In particular, the optimal MoS2(4.0 wt%)/Ag2CrO4 sample showed a MO degradation rate of 0.0064 min− 1, which was 4.0 and 12.8 times higher than that of pure Ag2CrO4 and MoS2, respectively. Such an enhancement could be ascribed to the function of MoS2 as electron collectors, which effectively promote separation and transportation of charge carriers. Furthermore, the stability and the plausible photocatalytic mechanism of the MoS2/Ag2CrO4 composite were also discussed.
