Abstract

Abstract: In this study we show that using gold palladium nanoparticles supported on a commercial aluminosilicate (HZSM-5) prepared using a wet co-impregnation method it is possible to produce hydrogen peroxide from molecular H₂ and O₂ via the direct synthesis reaction. Furthermore, we investigate the efficacy of these catalysts towards the oxidation of methane to methanol using commercially available H₂O₂. The effect of SiO₂: Al₂O₃ ratio and calcination temperature is evaluated and a direct correlation between support acidity and the catalytic activity towards H₂O₂ synthesis and methanol production is observed.
