摘要：

Hydrogen peroxide in high yields can be generated with high efficiency at mild conditions (25 degrees C and atmospheric pressure) with the formation of only environment-friendly by-products (N-2 and H2O) by a reduction of O-2 by hydrazine from its hydrate/salt with its complete conversion in a short reaction period (<= 0.5 h) using a easily separable supported Pd catalyst (Pd/Al2O3, Pd/Ga2O3 or Pd/C) in an acidic aqueous medium in the presence of bromide anions; the presence of both acid (protons) and bromide anions is essential for the selective reduction of O-2 by hydrazine to H2O2 and in their absence, the reaction leads only to the formation of water.
