H₂-D₂ Exchange Activity and Electronic Structure of Ag _x Pd_1-x Alloy Catalysts Spanning Composition Space.

ABSTRACT: Many computational studies of catalytic surface reaction kinetics have demonstrated the existence of linear scaling relationships between physical descriptors of catalysts and reaction barriers on their surfaces. In this work, the relationship between catalyst activity, electronic structure, and alloy composition was investigated experimentally using a Ag _x Pd_1-x Composition Spread Alloy Film (CSAF) and a multichannel reactor array that allows measurement of steady-state reaction kinetics at 100 alloy compositions simultaneously. Steady-state H₂-D₂ exchange kinetics were measured at atmospheric pressure on Ag _x Pd_1-x catalysts over a temperature range of 333-593 K and a range of inlet H₂
