Cellular Carbon Foam as a New Type of Supports for Palladium Catalysts

The applicability of a new carbon material—carbon foam with a cellular structure synthesized from the pyrolysis products of hydrocarbon gases—as a catalyst support was demonstrated. The modification of the carbon foam by the deposition of nanoglobular carbon particles on its surface made it possible to obtain a nonporous material with a specific surface area of <1 m2/g and an open-cell structure. Dispersed palladium particles uniformly distributed over the support surface were formed using a hydrolytic deposition method. It was found that the resulting catalyst with palladium immobilized on cellular carbon is promising for the selective hydrogenation of acetylene to ethylene.
