Abstract

The invention relates to the technical field of ordered porous materials, in particular to a highly ordered porous silica and a porous silicon carbonitride material and a preparation method and application thereof. Under a certain temperature, egg white adopted as template and structure-directing agent is stirred and then hydrolytically polycondensed through oil-soluble silicon source capable of controlling hydrolysis, and the template is removed from the obtained mixture under different roasting conditions, so that the ordered porous silica and the ordered porous silicon carbonitride material can be respectively obtained. The two materials have the unique ordered structure of the egg white, and have a specific surface area and good heat stability. Compared with the conventional method, the invention has the advantages of low cost, simple preparation technique, environment-friendliness and the like, and the obtained materials have a broad application prospect in fields such as the controlled release, separation, adsorption and catalysis of large biological molecules and proteins.

Description

technical field

[0001] The invention relates to the technical field of ordered porous materials, in particular to a highly ordered porous silicon dioxide and a porous silicon carbonitride. The invention also relates to a method for preparing the ordered porous silicon dioxide and ordered porous silicon carbonitride. Another aspect of the present invention relates to the use of the ordered porous silica in the fields of controlled release, separation, adsorption and catalysis of biological macromolecules and proteins. technical background

[0002] Egg white itself has the advantages of non-toxicity, easy foaming, emulsification, gelation, low price, good biocompatibility, and environmental friendliness, etc., and has a very broad application prospect. Most of the research on egg white is in the food industry and biology. There are relatively few researches on using egg white as a template to prepare various materials at home and abroad. Santi et al prepared NiFe through the...
