Embodiment 1
[0041] Dissolve 5 mL of tetra-n-butyl titanate in 17.5 mL of absolute ethanol, and stir for 30 min to form a transparent solution A;
[0042] Add 3.22g of zinc acetate dihydrate, 0.5g of melamine and 0.0125g of ammonium dihydrogen phosphate into 100mL of ethylene glycol solution, heat to 80°C under stirring, and form solution B after the solid is completely dissolved;
[0043] Slowly add solution A to solution B dropwise, add 1 mol / L hydrochloric acid solution dropwise to about pH=1.5 while stirring to obtain a sol, continue stirring for 1 hour, and obtain a gel after aging for 12 hours;
[0044] Place the gel in an oven at 100°C until it forms a solid;
[0045] Move the solid to the crucible and put it into the muffle furnace, heat up to 550°C at a rate of 5°C / min, keep warm for 2 hours, continue to heat up to 600°C at 2.5°C / min, keep warm for 2 hours and then cool, the product is passed through absolute ethanol, acetone and deionized After washing with water three times, va...
Embodiment 2
[0048] Dissolve 5 mL of tetra-n-butyl titanate in 17.5 mL of absolute ethanol, and stir for 30 min to form a transparent solution A;
[0049] Add 3.22g of zinc acetate dihydrate, 0.5g of melamine and 0.0125g of ammonium dihydrogen phosphate into 100mL of ethylene glycol solution, heat to 80°C under stirring, and form solution B after the solid is completely dissolved;
[0050] Slowly add solution A to solution B dropwise, add 1 mol / L hydrochloric acid solution dropwise to about pH=1.5 while stirring to obtain a sol, continue stirring for 1 hour, and obtain a gel after aging for 12 hours;
[0051] Place the gel in an oven at 100°C until it forms a solid;

Embodiment 3
[0055] Dissolve 5 mL of tetra-n-butyl titanate in 17.5 mL of absolute ethanol, and stir for 30 min to form a transparent solution A;
[0056] Add 3.22g of zinc acetate dihydrate, 1g of melamine, 0.025g of ammonium dihydrogen phosphate and 4mmol of 3-aminopropyltriethoxysilane into 100mL of ethylene glycol solution, and heat to 80°C while stirring. After the solid is completely dissolved Solution B is formed;
[0057] Slowly add solution A to solution B dropwise, add 1 mol / L hydrochloric acid solution dropwise to about pH=1.5 while stirring to obtain a sol, continue stirring for 3 hours, and obtain a gel after aging for 12 hours;
[0058] Place the gel in an oven at 110°C until it forms a solid;
[0059] Move the solid to the crucible and put it into the muffle furnace, heat up to 550°C at a rate of 5°C / min, keep warm for 2 hours, continue to heat up to 600°C at 2.5°C / min, keep warm for 2 hours and then cool, the product is passed through absolute ethanol, acetone and deionize...
