Carbon Nanofiber Supported Palladium Catalyst：The Effectsof Preparation Conditions on Palladium Dispersion

摘要

Temperature programmed desorption (TPR) and CO chemisorption were used to study the effects on palladiumdispersion of the preparation variables such as type of palladium precursor, calcination atmosphere, calcination temperatureand reduction temperature. Results indicated that all factors had great impact on the performance of the supported catalystand there was an optimal condition to obtain highest metal dispersion for carbon nanofibers supported catalyst.
