二酸化炭素，アンモニアおよび水蒸気による炭素電極の活性化

Abstract

In order to investigate the e鉦ect on the physical and chemical properties of porous carbon electrodes of gas activation，electrodes were prepared from charcoal，sawdust and graphite，and baked under nitrogen atmosphere at900℃．The carbon electmdes were subsequently treated with CO2，NH3，0r H、O vapor at various temperatures，and the physical properties of the activated carbon electrode were examined．Adsorption isotherms of H20vapor and N2gas on the carbon sample were also measured for the purpose of evaluating hydrophobicity and pore size distribution， and the re星ationship between the physical properties and the geometrical struct皿e was investgated。
