Title:
MONOLITHIC CATALYST WITH COBALT OXIDE NANOWIRE WRAPPED BY NITROGEN-DOPED CARBON, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/051896
Kind Code:
A1
Abstract:
Disclosed in the present application is an integral catalyst. The integral catalyst comprises a carrier and an active substance loaded on the carrier; the active substance comprises a nitrogen-doped carbon nanowire wrapped by cobalt oxide particles. Further disclosed in the present application is a preparation method for the integral catalyst. A cobalt oxide nanowire in the integral catalyst is wrapped by a nitrogen-doped carbon layer; the product quality is good; the conductivity is high; and the service life is long.
