Measurement of the Activation Energy of Oxygen Offering and Reproducing on Pt/HM,Pd/HM Catalysts
Abstract:
Pulse-reacting experiments of gaseous CO with catalyst surface oxygen and gaseous O_2 with reduced catalyst surface were designed in order to measure the activation energy of oxygen offering and the activation energy of oxygen reproducing on the catalyst surface. By the separate measurement of these two kinds of activation energy, the difference in behavior of Pt/HM and Pd/HM catalysts was explained.
The activation energy of oxygen offering on Pt/HM is lower than that on Pd/HM, but the oxygen reproducing activation energy on Pt/HM is higher than that on Pd/HM.
The activation energy of oxygen offering on Pt/HM is lower than that on Pd/HM, but the oxygen reproducing activation energy on Pt/HM is higher than that on Pd/HM.
