Embodiment 1
[0022] see Figure 1-2 , first use an analytical balance to weigh 1.7571g SnCl 4 ·5H 2 Add O to a beaker, add 50mL of deionized water, and stir it with a stirrer to completely dissolve it. Under stirring conditions, 0.3415g ZnCl 2 added to the above solution. The reaction was continued for 30 min while stirring, and 15 mL of NaOH solution with a concentration of 4 mol / L was added dropwise, and the resulting solution was alkaline. After continuing to stir for 1 h, the resulting mixed solution was transferred to a polytetrafluoroethylene-lined stainless steel autoclave, and hydrothermally reacted in a constant temperature drying oven at 180° C. for 24 h. Then cool at room temperature. After cooling to room temperature, filter and wash with water, and dry overnight at 60°C in a blast drying oven. The dried sample was ground in agate and calcined at 700°C for 6 hours to obtain Zn 2 SnO 4 / ZnO / SnO 2 composite photocatalyst. After 100 minutes of natural light irradiation, t...
