Abstract

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.

蜂窝碳泡沫作为钯催化剂的新型载体

摘要

展示了一种新型碳材料（具有由烃类气体的热解产物合成的具有孔结构的碳泡沫）作为催化剂载体的适用性。通过在其表面上沉积纳米球状碳颗粒而对碳泡沫进行改性，使得有可能获得比表面积＜1m ² / g且具有开孔结构的无孔材料。使用水解沉积法形成均匀分布在载体表面上的分散钯颗粒。发现具有固定在蜂窝状碳上的钯的所得催化剂有望将乙炔选择性加氢为乙烯。
