    摘要： 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. In another method, the specific surface area of a carbon material is further increased by removing the inorganic oxide of the reticulated skeleton in which the carbon material was formed.

    摘要： Methods of effectively utilizing yeast-containing waste products generated after yeast use can be applied to absorbing agents, drying agents, soil conditioners, catalysts, and other common applications in the same manner as to charcoal-based materials of other materials by carbonizing the waste product, but a new search was needed in order to broaden the industrial utilization of these products. By supporting a particulate or powdered charcoal-based material obtained by carbonizing a yeast-containing material on an electrically conductive gas-permeable base, an electrode can be obtained that is capable of the electrochemical reduction of oxygen. The present charcoal-based material can provide new applications that have not been hitherto proposed, in the sense that oxygen can be electrochemically reduced smoothly and at a small overvoltage (resistance), and a large electromotive force can be obtained, by placing the charcoal-based material at the intersection of the ion path and the oxygen path.
