Embodiment 1
[0025] According to the molar ratio of Ti:N:Cu element: 1:0.01:0.001, respectively weigh TiO 2 、H 2 NCONH 2 and CuCl 2 2H 2 O, the TiO 2 The solid powder was placed in a beaker of 15mL deionized water, and dissolved in H 2 NCONH 2 25 mL of acetic acid solution and CuCl 2 2H 2 O, then add 20 mL of ethanol with a solvent concentration of 95%, and place it in an ultrasonic wave for 30 min at a temperature of 20° C. to make it evenly mixed, and then add HCl to adjust the pH to 3;
[0026] The mixture system was transferred to a hydrothermal kettle, and placed in a programmed temperature-controlled drying oven for reaction at a temperature of 120°C and a static time of 6 hours;
[0027] Take it out after the reaction is finished, cool to room temperature, wash the mixture system with 95% ethanol and deionized water successively for 3 times, and centrifuge to obtain a white substance;
[0028] The obtained white substance was placed in a vacuum drying oven at a temperature ...
Embodiment 2
[0032] According to the molar ratio of Ti:N:Cu element: 1:0.02:0.003, respectively weigh TiO 2 、H 2 NCONH 2 and Cu(NO 3 ) 2 , the TiO 2 The solid powder was placed in a beaker of 15mL deionized water, and dissolved in H 2 NCONH 2 25mL of acetic acid solution and Cu(NO 3 ) 2 , and then add 20 mL of ethanol with a solvent concentration of 95%, and place it in an ultrasonic wave for 30 min at a temperature of 30 ° C to make it evenly mixed, and then add HCl to adjust the pH to 4;
