摘要：

Several supported and unsupported metal carbide catalysts were synthesized, characterized, and studied for their activity in the dehalogenation of CCl2F2 (CFC 12). Their catalytic properties were compared to those of a standard palladium catalyst. The turnover rates of the supported carbides were found to be higher than the unsupported carbides, but both deactivated quickly in the initial stages of reaction. X-ray photoelectron spectroscopic analysis of fresh and spent catalysts showed deposition of excessive amounts of carbon during the reaction which could be the cause of deactivation.
