Embodiment 1
[0014] Embodiment 1 A kind of mesoporous material
[0015] Dissolve 5p123 and 7 parts of ethylene glycol in 100 parts of 1.5 mol / L dilute hydrochloric acid, and stir at 500 rpm for 8 hours at a constant temperature of 35°C.
[0016] Add 15 parts of ethyl orthosilicate dropwise at a stirring speed of 800 rpm. After the addition is complete, continue stirring and raise the temperature to 80° C. at a rate of 2° C. / min, and then keep it for 24 hours to obtain solid A.
[0017] Dissolve 1.5 parts of lactide in ethanol and stir well. Then, while stirring, add 0.5 parts of concentrated sulfuric acid dropwise, then add solid A which is ground to 100 mesh, continue stirring for 6 hours, wait for the solvent to volatilize to obtain the mixture, keep it at 100°C for 6 hours, then quickly heat it to 130°C, keep it for 8 hours, and get a solid Substance B.
[0018] The solid material B was vacuum-dried at 50°C for 12 hours, then annealed at a high temperature in a hydrogen atmosphere for...
Embodiment 2
[0019] Embodiment 2 A kind of mesoporous material
[0020] Dissolve 8 parts of p123 and 9 parts of ethylene glycol in 150 parts of 1.0 mol / L dilute hydrochloric acid, and stir at 500 rpm for 10 h at a constant temperature of 30°C.
[0021] Add 10 parts of ethyl orthosilicate dropwise at a stirring speed of 700rpm. After the addition is complete, continue stirring and raise the temperature to 80°C at a rate of 2°C / min, and then keep it for 20 hours to obtain solid A.
