Abstract

In this study we show that using AuPd nanoparticles supported on a commercial titanium silicate (TS-1) 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. The effect of Au: Pd ratio and calcination temperature is evaluated as well as the role of Pt addition to the AuPd supported catalysts. The effect of Pt addition to AuPt nanoparticles is observed to result in a significant improvement in catalytic activity and selectivity to hydrogen peroxide with detailed characterisation indicating this is a result of selectively tuning the ratio of Pd oxidation states.
