Abstract
The invention discloses a method for preparing a mesoporous material by using perlite. According to the method, a silicon-aluminum ordered mesoporous material template is prepared by using the perlite as the material, and a silicon source and an aluminum source are not required, so that the material is low in cost and can be obtained easily, and the use ratio of the material is high.
Description
Technical field
The present invention relates to the preparation method of mesoporous material, be specifically related to a kind of method of utilizing perlite to prepare mesoporous material.
Background technology
Mesoporous material is the porous material of a kind of aperture between 2～50nm.The common employing hard template method of meso-porous carbon material is introduced carbon source in the duct of mesoporous template, under the katalysis of acid, makes precursor thermolysis carbonization, is deposited in mesoporous template duct, and template is fallen in high-temperature roasting, can obtain mesoporous material.
Perlite is used to building field more, and wherein silicone content accounts for 68～74% of total mass, and aluminium content is 12% left and right, is used for mesoporous material, and silicon and aluminum source can be provided simultaneously, and traditional raw material is cheap and easy to get relatively.
Summary of the invention
The present invention is a kind of method of utilizing perlite to prepare mesoporous material.
A kind of method of utilizing perlite to prepare mesoporous material comprises following process:
A. with perlite ball milling 5～8h, cross 100 mesh sieves, then with mineral acid agitation leach under constant temperature, time is 3～5h, filters, and getting supernatant liquid is silicon and aluminum source, silicon and aluminum source is joined in template, keep temperature to be 35 ℃ and stir 12h, change the autoclave crystallization over to and obtain mesoporous template.
B. carbon matrix precursor is dissolved in ethanol, then drips while stirring the vitriol oil, stir 5min.Then add above-mentioned mesoporous template, stir 3～6h, then heat up 100 ℃ and stir 10h.
C. with above-mentioned substance suction filtration, washing, drying, template is gone in high-temperature roasting, obtains mesoporous material.
Wherein, the constant temperature in described step a is 50～80 ℃, and stirring velocity is 450～500rpm.
Carbon matrix precursor in described step b comprises glucose, sucrose.
Positively effect of the present invention is: the present invention prepares sial ordered mesoporous material template take perlite as raw material, need not to add silicon source, aluminium source, and raw material is cheap and easy to get, and cost is low, and raw material availability is high.
Embodiment
A kind of method of utilizing perlite to prepare mesoporous material of embodiment:
A. with 1.8g perlite ball milling 8h, cross 100 mesh sieves, then with the agitation leach under constant temperature of 60g mineral acid, time is 5h, filter, getting supernatant liquid is silicon and aluminum source, and silicon and aluminum source is joined in 3.87g part template, keep temperature to be 35 ℃ and stir 12h, change the autoclave crystallization over to and obtain mesoporous template.
B. 7.5g sucrose is dissolved in 30mL ethanol, then drips while stirring the 0.53g vitriol oil, stir 5min.Then add above-mentioned mesoporous template, stir 6h, then heat up 100 ℃ and stir 10h.
C. with above-mentioned substance suction filtration, washing, drying, template is gone in high-temperature roasting, obtains mesoporous material.
The specific surface area of resulting materials is 120m
2/ g, pore volume are 0.20Ml/g.
