Direct synthesis of hydrogen peroxide using Au-Pd supported and ion-exchanged heteropolyacids precipitated with various metal ions

- Au-Pd catalysts prepared by ion exchange and impregnation methods with insoluble heteropolyacids as the support.
- The catalysts containing Cs and Rb prepared by ion exchange were shown to be extremely active for H2O2 synthesis.
- This is possible using reaction conditions that are suitable for potential applications.
