Abstract
Investigation of the interactions of beta-diketones was also done on alumina and gamma-alumina supported Pd catalysts in an attempt to alter Pd particle dispersion. Low-temperature redispersion of a sintered 5% Pd/gamma-alumina catalyst was most successful via exposure to oxygen and acetylacetone at ∼560 K for 8 hours. A bimodal distribution of CO desorption states was achieved, at 405 K and 585 K, with more CO desorbing from the high-temperature state. This indicated a decrease in Pd particle size relative to the sintered and, to some extent, untreated catalyst samples. Surface mechanisms were not investigated in this particular study.
