A composite of BiVO4-NiS was synthesized and used as a photocatalyst for the photocatalytic degradation of Congo red dye. BiVO4 and NiS were mixed in a 1:1 ratio. The composite was characterized on the basis of XRD, EDX, and FESEM data. The progress of photocatalytic degradation was monitored with a spectrophotometer. The effects of different parameters such as pH, dye concentration, amount of composite and light intensity on the degradation rate were investigated. The composite exhibited the highest catalytic activity in a neutral medium. It was found that higher activity, more stable nature, and recyclability of BiVO4-NiS composite were beneficial for the photodegradation of Congo red dye.
