用阶跃过渡应答法研究在ＰｄＡｇ／Ａｌ２Ｏ３催化剂上甲醇、氧、二氧化碳的吸附行为以及甲醇完全氧化反应应答。结果表明：甲醇为慢吸附、不可逆吸附，氧和二氧化碳为快速、可逆吸附；吸附态氧与吸附态甲醇的反应为快反应；甲醇在催化剂上的吸附是甲醇完全氧化反应的慢步骤。
The step transition reaction method was used to study the adsorption behavior of methanol, oxygen and carbon dioxide on PdAg / Al2O3 catalyst and the response of methanol to complete oxidation reaction. The results show that methanol is slowly adsorbed and irreversibly adsorbed. Oxygen and carbon dioxide are rapidly and reversibly adsorbed. The reaction of adsorbed oxygen with the adsorbed methanol is a fast reaction. The methanol adsorbed on the catalyst is a slow step in the complete oxidation of methanol.
