Effect of process parameters on the visible light photocatalytic performance of SnO by microwave synthesis

The effects of synthesis parameters, including pH, solvent, and output energy mode, on the synthesis and photocatalytic activity of SnO were investigated. The results exhibited that Cl-doped SnO samples with a particle size of approximately 50 nm were successfully obtained, with a BET surface area of approximately 7 m2/g. These parameters showed weak effects on phase composition, morphology, and particle size; however, they affected the degradation efficiency of SnO samples to MO. The optimum degradation efficiency of SnO samples to MO can be obtained by using an appropriate proportion of water and alcohol, acid condition, and three modes of output.
