Abstract

In situ production of hydrogen peroxide was achieved by the reaction of hydroxylamine and molecular oxygen over reusable activated carbon catalysts at ambient temperature with environmentally benign by-products (nitrogen and water). The yield of hydrogen peroxide was about 46% with the concentration of 0.39 wt% (114 mmol/L). Temperature-programmed desorption analysis and Fourier transformation infrared spectroscopy revealed that the oxygen-containing species, especially quinone/semiquinone-like structures, on the surface of activated carbon played a crucial role in the generation of H2O2, probably through the effective activation of oxygen molecule.
