Factors affecting the photocatalytic degradation of rhodamine B over MoS2/RGO under visible light
Abstract
In this work, factors affecting the photocatalytic degradation of rhodamine B over MoS2/RGO under visible light including pH, initial rhodamine B concentration, light source intensity and quencher existence were investigated. The reaction mechanism was also proposed. The results showed that MoS2/RGO composite exhibited highest photocatalytic performance under visible light irradiation in lightly acidic environment with 84% RhB degraded at pH = 4.05. Among the tested free radical killers, ammonium oxalate revealed the most significant effect on the photocatalytic degradation of RhB.
