Abstract

We report on a method for the controlled synthesis of a new type of high specific surface area mesoporous carbons denoted as the CMH family. By using mixtures of colloidal silica particles as templates it was possible to synthesize samples exhibiting 1,630 m2 g−1 specific surface area and 4.37 cm3 g−1 pore volume. CMH materials exhibit high thermal stability in oxygen and can be used as catalyst supports. This function was demonstrated by synthesizing Pt/CMH and Rh/CMH catalysts and testing them in the hydrogenation of cyclohexene. We have found Pt/CMH to be more stable and easier to regenerate than Rh/CMH.
