Title:
CARBON CATALYST WITH HIGHLY OPEN HIERARCHICAL PORE STRUCTURE AS WELL AS PREPARATION METHOD FOR AND USE OF CARBON CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/168799
Kind Code:
A1
Abstract:
The present invention provides a preparation method for a carbon catalyst with a highly open hierarchical pore structure, comprising: dissolving a carbon precursor and a double-salt templating agent in an alkali solution, and then stirring and mixing at room temperature to obtain a precursor solution; carrying out spray drying on the precursor solution to obtain a microsphere powder with a unique form, the tower top temperature in a spray drying process being 150-200℃; calcining the microsphere powder in an inert atmosphere at a calcination temperature of 600-1000℃; and removing the double-salt templating agent by means of water washing to obtain the carbon catalyst with a highly open hierarchical pore structure. In the present invention, the carbon catalyst prepared by combining a double-salt templating method with spray drying technology has excellent catalytic performance on an ozone oxidation reaction.
