Embodiment Construction
[0014] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection claimed by the present invention is not limited thereto.
[0015] The preparation method of the silver-doped titania catalyst of the present invention comprises the steps:
[0016] Step 1, add 2.5g of P25 titanium dioxide and 0.0394g of silver nitrate into 600ml of deionized water, and at the same time add 40mL of ethanol to the water to mix, and the ethanol is used as a hole scavenger;
[0017] Step 2, use a certain concentration of NaOH to adjust the pH of the mixed solution in step 1 to 11-12, and then pour 30minN into the mixed solution 2 (deoxygenation);
[0018] Step 3, under continuous stirring, irradiate the mixed solution in step 2 with a 250W ultraviolet lamp for 10 hours, and after irradiation, separate the suspension from solid and liquid in a centrifuge, and wash the obtained solid with deionized water ...
