Structure sensitivity of methane dissociation on palladium single crystal surfaces

Abstract

Palladium single crystals have been found to be active for the C-H bond dissociation of methane in the temperature range 400-600 K, and the activities of the presently investigated Pd(111) and Pd(311) surfaces are compared with previously studied Pd(679). Structure sensitivity is reported that spans an order of magnitude in terms of the rates in the order Pd(111)
