抄録

The ruthenium-porous carbon composites were prepared from a commercial chelate resin (IRC748) with the adsorption of aqueous ruthenium ion (Ru<SUP>3+</SUP>) by carbonization (N<SUB>2</SUB>) and activation (CO<SUB>2</SUB>) at 800°C. The specific surface area and pore volume of the composites depended on the amount of Ru<SUP>3+</SUP> adsorbed on the chelate resin. The ruthenium ion changed to metallic ruthenium when the ruthenium content of the composite (X<SUB>Ru</SUB>) was below 10 mass%. When X<SUB>Ru</SUB> was above 36 mass%, not only metallic ruthenium but also ruthenium oxide (RuO<SUB>2</SUB>) were found in the composite. The crystalline size of the ruthenium compounds from the Scherre equation were almost 30-33 nm by XRD analysis. The ruthenium-porous carbon composites were applied to electrode of capacitor. The specific capacitances (C<SUB>S</SUB>) of the composite were stable in the charge and discharge experiment. The C<SUB>S</SUB> depended on X<SUB>Ru</SUB>; when X<SUB>Ru</SUB> was small (0-30 mass%), Cs deceased linearly with increasing X<SUB>Ru</SUB>. However, C<SUB>S</SUB> increased with increasing X<SUB>Ru</SUB> (> 30 mass%). The effect of ruthenium content on the capacitance was also discussed by comparing the experimental results of physical mixing of porous carbon and ruthenium oxide.
