The direct synthesis of hydrogen peroxide (DSHP) from H2 and O2 is conceptually the most ideal and straightforward reaction for producing H2O2 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 H2O2 from H2 and O2 prepared by the immobilization of Pd nanocatalysts onto a functionalized resin. The continuous production of 8.9 wt % H2O2 and high productivity (180 g of H2O2 (g of Pd)鈭? h鈥?) 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.
