Abstract
Official abstract text for this publication.
A porous carbon material composite formed of a porous carbon material and a functional material and equipped with high functionality. The porous carbon material composite is formed of (A) a porous carbon material obtainable from a plant-derived material having a silicon (Si) content of 5 wt % or higher as a raw material, said porous carbon material having a silicon (Si) content of 1 wt % or lower, and (B) a functional material adhered on the porous carbon material, and has a specific surface area of 10 m 2 /g or greater as determined by the nitrogen BET method and a pore volume of 0.1 cm 3 /g or greater as determined by the BJH method and MP method.
First claim
Opening claim text (preview).
What is claimed is: 1 . A process for producing a porous carbon material composite, comprising the steps of: carbonizing a plant-derived material at from 800° C. to 1,400° C.; treating the carbonized material with an acid or alkali to obtain a porous carbon material; and then causing a functional material to adhere on the porous carbon material. 2 . The process for producing the porous carbon material composite according to claim 1 , further comprising applying activation treatment after the treatment with the acid or alkali but before the adhesion of the functional material on the porous carbon material. 3 . The process for producing the porous carbon material composite according to claim 1 , wherein: the plant-derived material has a silicon content of 5 wt % or higher; the porous carbon material has a silicon content of 1 wt % or lower; and the porous carbon material composite has a specific surface area of 10 m 2 /g or greater as determined by the nitrogen BET method and a pore volume of 0.1 cm 3 /g or greater as determined by the BJH method and MP method. 4 . The process for producing the porous carbon material composite according to claim 1 , the functional material is a magnetic material. 5 . The process for producing the porous carbon material composite according to claim 1 , wherein the functional material shows an optical property. 6 . The process for producing the porous carbon material composite according to claim 1 , wherein the functional material shows a photocatalytic property. 7 . The process for producing the porous carbon material composite according to claim 1 , wherein the functional material is composed of a noble metal, noble metal alloy, oxide semiconductor or compound semiconductor. 8 . The process for producing the porous carbon material composite according to claim 1 , wherein the functional material is composed of an external stimulus responsive substance and a releasable substance.
