Examples
preparation example 1
[0037] Preparation example 1: ① Take 20kg of silicon dioxide, 1kg of titanium dioxide and 0.6kg of zirconium dioxide, grind them, place them at a temperature of 900°C, and calcinate them for 4 hours. After cooling, a calcined material is obtained;
[0038] ②Take 0.2kg of silver nitrate powder, add 30kg of water to it, and stir evenly to obtain a silver nitrate solution; add 2kg of calcined material to the silver nitrate solution, and stir at a temperature of 20-30°C for 10 minutes to obtain a mixed solution;
[0039] ③Add 0.2kg of glucose and 1kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 10min, filter with suction, then wash with 50wt% ethanol solution, and dry at 80°C for 6h to obtain silver-loaded silica.
preparation example 2
[0040] Preparation Example 2: ① Take 25kg of silicon dioxide, 1.5kg of titanium dioxide and 0.8kg of zirconium dioxide, grind them, place them at a temperature of 925°C, and calcinate them for 5 hours. After cooling, a calcined material is obtained;
[0041] ②Take 0.25 kg of silver nitrate powder, add 30 kg of water to it, and stir evenly to obtain a silver nitrate solution; add 3 kg of calcined material to the silver nitrate solution, and stir for 15 minutes at a temperature of 25°C to obtain a mixed solution;
[0042] ③Add 0.3kg of glucose and 1.5kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 15min, filter with suction, then wash with 50wt% ethanol solution, and dry at 85°C for 7h to obtain the Silver silica.
preparation example 3
[0043]Preparation example 3: ① Take 30kg of silicon dioxide, 2kg of titanium dioxide and 1kg of zirconium dioxide, grind them, place them at a temperature of 950°C, and calcinate them for 6 hours. After cooling, a calcined material is obtained;
[0044] ② Take 0.3 kg of silver nitrate powder, add 30 kg of water to it, and stir evenly to obtain a silver nitrate solution; add 4 kg of calcined material to the silver nitrate solution, and stir for 20 minutes at a temperature of 30°C to obtain a mixed solution;
[0045] ③Add 0.4kg of glucose and 2kg of 10wt% sodium hydroxide aqueous solution to the mixed solution, stir for 20min, filter with suction, then wash with 50wt% ethanol solution, and dry at 90°C for 8h to obtain silver-loaded silica.
