The Chemisorption of Hydrogen on Zinc Oxide. I. Effect of Chemisorption on the Electrical Conductivity of Zinc Oxide

概要

論文の詳細を見る
The conductivity change caused by the chemisorption of hydrogen was investigated with oxidized and reduced zinc oxide. In the former case the conductivity after hydrogen was admitted into the sorption vessel increased autocatalytically until a maximum rate was attained. The behavior was attributed to the decrease in concentration of adsorbed oxygen atom and the activation energy for this decrease was estimated to be 18 kcal. The adsorption on reduced zinc oxide revealed no significant change in conductivity below 110℃, while it produced marked increase in conductivity at higher temperatures. The results indicate that the chemisorption taking place above 110℃ is of a different type from that at lower temperature.
