The Direct Synthesis of H2O2 and Selective Oxidation of Methane to Methanol Using HZSM-5 Supported AuPd Catalysts

摘要

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 H-2 and O-2 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.
