Direct synthesis of H2O2 from H2 and O2 over palladium nanocatalysts immobilized on functionalized resin |
| 초록 |
Hydrogen peroxide, widely used in almost all industrial areas, is commercially produced by the anthraquinone oxidation (AO) process. However, this process requires significant energy input and generates waste, which has a negative effect on its sustainability and production costs. An alternative method is direct synthesis of H2O2 (DSHP) from H2 and O2. The DSHP process is conceptually the most ideal and straight forward reaction for producing H2O2 in industry. However, preparations of precisely tailored catalysts are still under progress for large scale production of H2O2. Here, we present highly efficient and industrially relevant catalyst 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 H2O2 g 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 H2O2 from H2 and O2 |
