Method for preparing mesoporous material by non-surface activator process

Abstract

The invention discloses a preparing method of medium hole material with non-surface activator method, which comprises the following steps: mixing metyl group with hydrogen polysiloxane and alcohol; adding into NaOH; vigorous stirring; dipping into deionized water with equivoluminal metyl group hydrogen polysiloxane; stirring; adding into silicic acid carbethoxyl; vigorous stirring; strewing and aging; drying; getting solid; grinding to powder; washing with deionized water; drying; getting the product. This invention possesses medium phase of 3D worm-hole like pore path with the specific surface area in the range of 450-700m2 / g and hole volume in the range of 0. 4-1. 8cm3g-1.

Description

technical field

[0001] The invention relates to a method for synthesizing mesoporous materials, in particular to preparing organic-inorganic hybrid mesoporous materials by using a sol-gel method. technical background

[0002] Mesoporous material is a new type of nanomaterial with a pore size of 2-50nm. It is also a "production base" for other nanomaterials and a "microreactor" for many green chemical reactions. Pure silicon or silicon-alumina mesoporous molecular sieves with adjustable pore size and high specific surface area have very broad application prospects in catalytic reactions, adsorption and separation, preparation of nanomaterials, optical and electromagnetic materials. At present, it has become one of the research hotspots in the fields of chemical industry, information communication, biotechnology, and environmental energy.

[0003] In 1992, the staff of Mobil successfully prepared M41S silica (aluminum)-based mesoporous molecular sieves with a pore size larger...
