Use of Pd/Activated Carbon Fiber Catalyst to Dehydrogenate Cyclohexane

Porous carbon materials have attracted growing attention among the different types of supports used in heterogeneous catalysis because of certain favorable characteristics, which are essentially their resistance to acidic/basic media, significant pore and surface tailorability, and ease of recovery of catalytic metals via combustion of the support material. Carbon fibers typically feature a relatively low surface area of 50–350 m/g when compared to activated carbons and activated carbon fibers [1]. Activated carbon fibers (ACFs) depict a comparatively contemporary variety of porous carbon material with a number of important advantages such as a high apparent specific surface area, generally in the range of 1500–3000 m/g, and a high adsorption capacity, as well as very rapid adsorption kinetics from the gas and liquidphases [2]. ACFs have attracted considerable interest because of their wide applicability for separation purposes and as catalyst supports.
