Title:
NITROGEN-DOPED HOLLOW HIERARCHICALLY-POROUS CARBON MICROSPHERE WITH HIGH OXYGEN CONTENT, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/168800
Kind Code:
A1
Abstract:
Provided in the present invention is a preparation method for a nitrogen-doped hollow hierarchically-porous carbon microsphere with a high oxygen content, the method comprising: dissolving histidine and a salt template agent in an aqueous hydrochloric acid solution, and then stirring and mixing same at room temperature to obtain a precursor solution; subjecting the precursor solution to spray-drying so as to obtain a hollow microsphere having a unique morphology, wherein the tower top temperature during the spray-drying process is 150-200ºC; calcining the hollow microsphere in an inert atmosphere, wherein the calcining temperature is 600-1000ºC; and removing the salt template agent by means of washing with water to obtain the nitrogen-doped hollow hierarchically-porous carbon microsphere with a high oxygen content. The hollow carbon microsphere of the present invention, which is prepared by a salt template method combined with a spray-drying technique, has a good catalytic performance in an ozone oxidation reaction.
