Title:
METHOD OF MANUFACTURING METAL OXIDE-POROUS BODY COMPOSITE, AND COMPOSITE OF POROUS CARBON MATERIAL AND METAL OXIDE
Document Type and Number:
WIPO Patent Application WO/2019/049905
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a metal oxide-porous body composite by causing a metal oxide to be carried in fine pores of a porous body. The method comprises: a step (1) of placing a porous body under reduced pressure and heating the porous body to a decomposition temperature of a metal oxide precursor; a step (2) of intermittently repeatedly supplying the metal oxide precursor to the porous body under reduced pressure and being heated to cause a decomposed material of the precursor to become precipitated in the fine pores of the porous body; and, after step (2), a step (3) of preparing a metal oxide-porous body composite by heating the porous body, with the precursor and/or the decomposed material thereof having been precipitated in the fine pores, under inert atmosphere and at a temperature higher than in step (1) and (2). With the method, it becomes possible to relatively easily prepare a composite of a porous carbon and a metal oxide in which the metal oxide is uniformly precipitated in the interior of a nanostructure. The present invention relates to a composite of a porous carbon material and a metal oxide in which the metal oxide is partly or entirely present in the fine pores of the porous carbon material. The composite is a composite of a porous carbon and a metal oxide in which the metal oxide is precipitated uniformly in the interior of a carbon nanostructure.
