Title:
TRANSITION METAL COMPOUND-HYBRIDIZED AND NITROGEN-DOPED POROUS CARBON MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/238912
Kind Code:
A1
Abstract:
Provided is a transition metal compound-hybridized and nitrogen-doped porous carbon material. The structure of the porous carbon material contains nitrogen-doped porous graphitized carbon and a transition metal compound, wherein the transition metal compound is hybridized in the nitrogen-doped porous graphitized carbon, and the transition metal compound is selected from vanadium nitride, oxygen-doped titanium nitride, WC, W2C/W, or WC/W2C/W. In the porous carbon material, the transition metal compound is uniformly distributed on the porous carbon and is not easy to agglomerate, and the porous carbon material has a high specific surface area. Also provided is a preparation method for the porous carbon material.
