Procedure
8.7876 g of SnCl4.5H2O were dissolved in 100.0 ml of water, and, 2.1 ml of 12M HNO3 were added to obtain a solution with a molar ratio of HNO3 to SnCl4 being 1:1. 80 ml of the solution were put in a thermal bomb and the thermal bomb was heated in a high temperature oven at 150° C. for 12 h, and then cooled to room temperature and white precipitates formed. The precipitates were repeatedly washed with deionized water and filtrated with suction until no Cl- can be detected by a solution of AgNO3. The precipitates were then dried and put in a high temperature oven and the temperature of the oven was increased at a rate of 5° C./min to 200° C. to calcine the precipitates for 6 h and then cooled the oven at a rate of 5° C./min to room temperature to obtain SnO2 powders.
