Abstract:
(EN) 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.
(FR) La présente invention concerne un procédé de fabrication d'un composite de corps poreux d'oxyde métallique en amenant un oxyde métallique à être transporté dans des pores fins d'un corps poreux. Le procédé comprend : une étape (1) consistant à placer un corps poreux sous pression réduite et à chauffer le corps poreux jusqu'à une température de décomposition d'un précurseur d'oxyde métallique ; une étape (2) d'alimentation répétée intermittente du précurseur d'oxyde métallique au corps poreux sous pression réduite et étant chauffé pour provoquer la précipitation d'un matériau décomposé du précurseur dans les pores fins du corps poreux ; et, après l'étape (2), une étape (3) de préparation d'un composite de corps poreux d'oxyde métallique par chauffage du corps poreux, le précurseur et/ou le matériau décomposé de celui-ci ayant été précipité dans les pores fins, sous atmosphère inerte et à une température supérieure à l'étape (1) et (2). Avec le procédé, il devient possible de préparer relativement facilement un composite d'un carbone poreux et d'un oxyde métallique dans lequel l'oxyde métallique est précipité uniformément à l'intérieur d'une nanostructure. La présente invention concerne un composite d'un matériau de carbone poreux et d'un oxyde métallique dans lequel l'oxyde métallique est partiellement ou entièrement présent dans les pores fins du matériau de carbone poreux. Le composite est un composite d'un carbone poreux et d'un oxyde métallique dans lequel l'oxyde métallique est précipité uniformément à l'intérieur d'une nanostructure de carbone.
