Palladium Nanocatalysts Immobilized on Functionalized Resin for the Direct Synthesis of Hydrogen Peroxide from Hydrogen and Oxygen

The direct synthesis of hydrogen peroxide (DSHP) from H 2 and O 2 is conceptually the most ideal and straightforward reaction for producing H 2 O 2 in industry. However, precisely tailored catalysts are still in progress for large scale production. Here, we report highly efficient and industrially relevant catalysts for the direct synthesis of H 2 O 2 from H 2 and O 2 prepared by the immobilization of Pd nanocatalysts onto a functionalized resin. The continuous production of 8.9 wt % H 2 O 2 and high productivity (180 g of H 2 O 2 (g of Pd) −1 h –1 ) is achieved under intrinsically safe and less-corrosive conditions without any loss of activity. We expect this approach is a substantial improvement of nanocatalysts for direct synthesis of hydrogen peroxide from hydrogen and oxygen and will greatly accelerate the industrially relevant process of on site production of hydrogen peroxide soon.
