[0020] Example 1:
[0021] 1) Preparation of titanium dioxide: Dissolve 5 mL of titanium tetraisopropoxide in 30 mL of isopropanol, adjust the pH of the solution to 1 with concentrated hydrochloric acid; take another 0.5 mL of deionized water and dissolve it in 8 mL of isopropanol; mix the above two solutions Alternately filter through cellulose filter paper, and then use 50 mL of ethanol to wash away unreacted titanium tetraisopropoxide; finally, place the cellulose filter paper attached with titanium dioxide gel at 450 o In an air atmosphere, remove the cellulose filter paper to obtain titanium dioxide;
[0022] 2) Dissolve 0.003 mol of sodium dihydrogen phosphate in 20 mL of deionized water, and then take 0.06 g of titanium dioxide to ultrasonically disperse it in the above solution;
[0023] 3) Dissolve 0.004mol of silver acetate in 20mL of deionized water, slowly add it dropwise to the solution obtained in step 2 under magnetic stirring conditions, continue to react for...
Example Embodiment
[0024] Example 2:
[0025] 1) Same as step 1 of Example 1;
[0026] 2) Dissolve 0.006mol of potassium dihydrogen phosphate in 20mL of deionized water, and then take 0.08g of titanium dioxide to ultrasonically disperse it in the above solution;
[0027] 3) Dissolve 0.008mol of silver acetate in 20mL of deionized water, slowly add it dropwise to the solution obtained in step 2 under magnetic stirring conditions, continue to react for 6 hours after the dropwise addition, filter, wash, 60 o The silver phosphate / titanium dioxide composite material was obtained by vacuum drying under C.
Example Embodiment
[0028] Example 3:
[0029] 1) Same as step 1 of Example 1;
[0030] 2) Dissolve 0.003 mol of sodium dihydrogen phosphate in 20 mL of deionized water, and then take 0.06 g of titanium dioxide to ultrasonically disperse it in the above solution;
[0031] 3) Dissolve 0.004mol of silver nitrate in 20mL of deionized water, slowly add it dropwise to the solution obtained in step 2 under magnetic stirring conditions, continue to react for 6 hours after the dropwise addition, filter, wash, 60 o The silver phosphate / titanium dioxide composite material was obtained by vacuum drying under C.
