Controlling the Morphology of Carbon GelsControl de la morfología de los geles de carbónMukai, R. S.Geles de carbónCarbon gels[EN] Carbon gels are unique porous carbons, which are typically obtained through the carbonization of resorcinol-formaldehyde gels. This material is practically an aggregate of nanometer-sized carbon particles. Nanopores, mostly in the size range of mesopores, exist between the particles. Smaller pores, micropores being the majority, also exist within the particles. Therefore, this material has a hierarchical pore system in which short micropores are directly connected to mesopores. The precursor of carbon gels can be obtained through sol-gel transition. Therefore there is a high possibility that the morphology of the resulting carbon can be easily controlled using various molding methods. We have actually challenged the controlling of the morphology of carbon gels, and have succeeded in obtaining them in the form of disks, microspheres and microhoneycombs. Details of such carbon gels will be reported.[ES] Los geles de carbón son materiales porosos únicos que se obtienen normalmente mediante la carbonización de geles de resorcinol-formaldehído. Este material es prácticamente un agregado de parículas de carbono nanométricas. Los nanoporos, mayoritariamente en el intervalo de tamaño de los mesoporos, existen entre las partículas. Los poros más pequeños, mayoritariamente microporos existen también dentro de las partículas. Por tanto, este material tiene un sitema jerárquico de poros en el que los cortos microporos están directamente conectados a los mesoporos. El precursor de los geles de carbon se puede obtener a través de una transición soil-gel. Por tanto hay alta posibilidad de que la morfología del carbón resultante se pueda controlar fácilmente usando diferentes métodos de moldeo. De hecho, hemos afrontado el reto de controlar la morfología de los geles de carbón y hemos tenido éxito al obtenerlos en forma de discos, microesferas y micro panales de abejas. Los detalles de estos geles de carbón se presentarán en este trabajo.Peer reviewedGrupo Español del Carbón201320132012info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/81798reponame:DIGITAL.CSIC.
