Abstract
The hydrodeoxygenation of m-cresol has been studied on SiO2- and ZrO2-supported Pd catalysts. Regardless of metal dispersion, the latter exhibit greatly enhanced selectivity to toluene. This remarkable support effect can be explained in terms of a mechanism that involves a keto-intermediate tautomer favored by oxophilic sites on the support.
