Title:
NANOPOROUS SOLID ACID BASED ON SILICA AEROGEL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/126959
Kind Code:
A1
Abstract:
The present invention provides a nanoporous solid acid based on a silica aerogel and a preparation method therefor. In the nanoporous solid acid based on a silica aerogel of the present invention, the solid acid is dispersed in a nanoporous structure of the silica aerogel, and the weight ratio of the solid acid to the silica aerogel is 1:10-100. In addition, the present invention also provides use of the nanoporous solid acid based on a silica aerogel in catalyzing the Maillard reaction intermediate pyrolysis. The research finds that the nanoporous solid acid based on a silica aerogel of the present invention has higher catalytic activity than the conventional solid acid to the Maillard reaction intermediate pyrolysis, and can promote release of aroma substances.
