The direct synthesis of H2O2 and selective oxidation of methane to methanol using HZSM-5 supported AuPd catalysts

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
