Patent number: 7390474Abstract: Conventional porous carbon materials obtained by carbonizing an organic gel were prone to shrinkage during their manufacture, in the course of which the density rose and the specific surface area decreased. Another problem was that density and specific surface area were difficult to control after an organic gel had already been formed. In the present invention, a carbon material with a large specific surface area is formed by forming a composite porous material having a reticulated skeleton and composed of a dry gel of an inorganic oxide, and taking advantage of the reaction of this dry gel of an inorganic oxide as a structural support. In one method, a carbon material is formed in this reticulated skeleton in a state in which the characteristics of a dry gel of an inorganic oxide with a large specific surface area are maintained.Type: GrantFiled: April 29, 2004Date of Patent: June 24, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masa-aki Suzuki, Hidehiro Sasaki, Yasunori Morinaga, Masahiro Deguchi, Yuka Yamada, Nobuyasu Suzuki
