Embodiment 1
[0018] Add tetraethyl orthosilicate and ethanol into a 250ml three-neck flask at a ratio of 1.2:1 by volume, add 30ml of water, take a water bath to 50°C, and use HNO 3 Adjust pH=4, add a small amount of cetyl dimethyl ammonium bromide as a surfactant, stir for 3 hours to prepare SiO 2 Sol. Another 20gSb 2 o 3 Mix it with 2Oml of distilled water in a 50ml three-neck flask, heat to 80°C and stir to stabilize, then add 3ml of triethanolamine, stir for 15min, then heat up to 90°C, then add 3ml of H 2 o 2 (dropwise), continue to stir for 90min until the solution changes from a white suspension to a colorless transparent antimony sol.
[0019] The two sols were thoroughly mixed according to 6:1 (volume ratio), and adjusted to pH=10. The polystyrene template and the mixed solution were assembled by impregnation, ultrasonication, and suction filtration by the in-situ method, and then dried at 70°C for 1 hour, and then programmed to heat up to 600°C for 8 hours under the conditio...
Embodiment 2
[0023] Add tetraethyl orthosilicate and ethanol into a 250ml three-neck flask at a ratio of 1.2:1 by volume, add 30ml of water, take a water bath to 50°C, and use HNO 3 Adjust pH=4, add a small amount of cetyltrimethylammonium bromide as a surfactant, stir for 3 hours to prepare SiO 2 Sol. Another 25gSb 2 o 3 Mix with 20ml in a 50ml three-neck flask, heat to 80°C and stir to stabilize, then add 3ml of triethanolamine, stir for 15min, then heat up to 90°C, then add 3ml of H 2 o 2 (dropwise), continue to stir for 90min until the solution changes from a white suspension to a colorless transparent antimony sol.
[0024] The two sols were thoroughly mixed according to 7:1 (volume ratio), and adjusted to pH=10. The polystyrene template and the mixed solution were assembled by impregnation, ultrasonication, and suction filtration in situ, and then dried at 80°C for 1 hour, extracted with acetone and tetrahydrofuran, and repeated 4 times. The macroporous Sb 2 o 5 / SiO 2 Mater...
