Nano-SnS2 and TiO2 powders were synthesized with a solution reaction method and a sol-gel method respectively. XRD and AFM and spectrophotometry were used for characterization of the powders. The photodegradation of methyl orange on the TiO2 powders and a mixture of SnS2 and TiO2 powders were studied respectively. Effect of pH value on the degradation of methyl orange solution was studied. The experiment result indicated that degradation rate of methyl orange was larger on the mixture of SnS2 and TiO2 powders than on the TiO2 powders and was larger in high pH value than in low pH value. Benzyl in the methyl orange can be further photodecomposed in the condition of alkaline solution. The present article discuss the useful patents in the field of photocatalytic property of mixture of SnS2 and TiO2 powders.
