Abstract

WP2O7 prepared by convenient technique was used as a support for platinum group metals. WP2O7, Pt/WP2O7 and Pd/WP2O7 were characterized by powder X-ray diffraction, Ar physisorption, SEM-EDX, and were tested in the H oxidation reaction. The activity of Pt/WP2O7 and Pd/WP2O7 catalysts was compared with that of Pt/Al2O3 and Pd/Al2O3 catalysts containing the same amount of supported platinum metals. It was shown that the Pt/WP2O7 and Pd/WP2O7 catalysts exhibit enhanced activity attributed to synergistic effect realizes between Pt(Pd) metal and WP2O7 phase.
