Example Embodiment
[0052] Example 1
[0053] 1) Add 66mL of 10mol / L sodium hydroxide concentrated alkali to 100mL of PTFE liner, then add 0.66g of titanium dioxide (anatase phase) powder (particle size 25nm), stir until evenly mixed, Form a white turbid suspension;
[0054] 2) Seal the polytetrafluoroethylene lining into the autoclave, start heating in the airtight drying box and react at 180℃ for 24h;
[0055] 3) After the reaction is completed, cool to room temperature with the furnace, then obtain the original product by vacuum filtration, and place it in a drying oven at 60°C for 8 hours;
[0056] 4) After immersing the dried sample in step 3) in 0.1 mol / L dilute hydrochloric acid for 24 hours, it is washed with deionized water by centrifugation to neutrality, and then dried in a drying oven;
[0057] 5) Place the sample obtained in step 4) in a corundum ark, and start heating in a muffle furnace, heating at 500° C. for 2 hours, and cooling to room temperature in the furnace after the reaction is com...
