采用水热法制备锗酸锶晶体纳米线,并研究了其对龙胆紫的光催化性能。结果表明:随着光催化时间的延长和锗酸锶纳米线用量的增加,龙胆紫的降解率均呈上升趋势;但随着龙胆紫溶液初始浓度的增加,其降解率逐步降低。在光催化时间4h、锗酸锶纳米线用量10mg、龙胆紫溶液初始浓度10mg/L的条件下,锗酸锶纳米线光催化降解龙胆紫的效果最好,龙胆紫的降解率可达89.59%。
Hydrothermal method was used to prepare SrGeO nanowires, and the photocatalytic activity of gentian violet was studied. The results showed that with the increase of photocatalytic time and the increase of the amount of strontium nanowires, the degradation rate of gentian violet tended to increase. However, the degradation rate of gentian violet decreased gradually with the initial concentration of gentian violet solution increasing. The photocatalytic degradation of gentian violet by strontium germitate nanowires was the best under the conditions of photocatalytic time 4h, strontium germinate nanowire amount 10mg and gentian violet solution initial concentration 10mg / L. The degradation rate of gentian violet Up to 89.59%.
