Comparative Study on Low Temperature Methane Activation over Cobalt and Ruthenium Supported on Al_2O_3, SiO_2, and NaY

摘要

Structure of the alumina, silica and NaY zeolites supported Co and Ru catalysts determined by XRD, XPS and TPR, and its activity in low temperature methane activation measured by deuterium uptake were investigated. Formation of CH_x species is affected by the nature of metal (e.g. methane dissociation occurs on Pt to a lesser extent than on Co and Ru), by the metal/support interaction causing difficulty in reduction metals and the metal particle size.
