Abstract

The ruthenium-porous carbon composites were prepared from a commercial chelate resin (IRC748) with the adsorption of aqueous ruthenium ion (Ru³⁺) by carbonization (N₂) and activation (CO₂) at 800°C. The specific surface area and pore volume of the composites depended on the amount of Ru³⁺ adsorbed on the chelate resin. The ruthenium ion changed to metallic ruthenium when the ruthenium content of the composite (X_Ru) was below 10 mass%. When X_Ru was above 36 mass%, not only metallic ruthenium but also ruthenium oxide (RuO₂) 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_S) of the composite were stable in the charge and discharge experiment. The C_S depended on X_Ru; when X_Ru was small (0-30 mass%), Cs deceased linearly with increasing X_Ru. However, C_S increased with increasing X_Ru (> 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.
