Embodiment 1
[0023] At 35°C, the template agent dehydroabietyltrimethylammonium bromide (DTAB) and methylamine were dissolved in deionized water, and tetraethyl orthosilicate (TEOS) was added under stirring conditions. The moles of the above raw materials than TEOS ׃DTAB ׃methylamine ׃H 2 O=1.0׃0.15׃2.68׃699.06, continue to stir for 30 s, put it into a hydrothermal reaction kettle after standing for 24 h, crystallize at 100 °C for 12 h, wash and filter and dry in an oven at 100 °C for 6 h, Obtain silicon dioxide precursor powder.
Embodiment 2
[0025] At 30°C, the template agent dehydroabietyltrimethylammonium bromide (DTAB) and ethylamine were dissolved in deionized water, and tetraethyl orthosilicate (TEOS) was added under the condition of stirring. than TEOS ׃DTAB ׃ethylamine ׃H 2 O=1.0׃0.15׃2.68׃699.06, continue to stir for 30s, put it into a hydrothermal reaction kettle after standing for 24h, crystallize at 100°C for 24h, wash and filter and dry in an oven at 95°C for 6h to obtain Silicon precursor powder.
Embodiment 3
[0027] At 38°C, the template agent dehydroabietyltrimethylammonium bromide (DTAB) and propylamine were dissolved in deionized water, and tetraethyl orthosilicate (TEOS) was added under stirring conditions. The molar ratio of the above raw materials for TEOS ׃DTAB ׃ propylamine ׃H 2 O=1.0׃0.15׃2.68׃699.06, continue to stir for 30s, put it into a hydrothermal reaction kettle after standing and aging for 24h, crystallize at 100°C for 48h, wash and filter and dry in an oven at 100°C for 5h to obtain carbon dioxide Silicon precursor powder.
