The strontium germinate crystal nanowires were prepared by hydrothermal method, and their photocatalytic performance for degrading gentian violet was investigated. The results show that the degradation rate of gentian violet increases by prolonging the photocatalysis time and increasing the dosage of strontium germinate crystal nanowires, but gradually decreases with the increase of initial concentration of gentian violet solution. Under the conditions of photocatalysis time of 4 h, strontium germinate nanowires dosage of 10 mg and initial concentration of gentian violet solution of 10 mg/L,the optimal photocatalytic effect of the strontium germinate nanowires for degrading gentian violet can be obtained, with a degrada- tion rate of 89. 59%.
