文摘

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.
