Abstract

A novel [PtMo6]/MgO ensemble catalyst was prepared using a [PtMo6O24]8−heteropolyanion precursor and characterized, by EXAFS. Analysis of the EXAFS spectra showed that after calcination at temperatures above 673 K platinum and molybdenum atoms interact with the support. Platinum ions (Pt4+) replace surface Mg2+ ions of the MgO carrier, while Mo6+ ions locate on the magnesia surface in a distorted octahedrally, coordinated framework. Catalytic tests using i-butane, n-butane and propane dehydrogenation as probe reactions showed that the novel ensemble catalyst exhibits a much better catalytic performance compared to conventionally prepared catalysts.
