In this study, the influence of the surface oxygen groups of activated carbons (ACs) on the decomposition of H2<\/sub>O2<\/sub> and the consequent \"radical<\/sup>OH radicals generation is investigated. The oxidation of pre-adsorbed volatile organic compounds by H2<\/sub>O2<\/sub> is also studied. Four ACs, with low percentage of inorganic matter (<0.2%), similar textural properties but differing in their surface oxygen content were evaluated. The surface oxygen groups of the ACs were characterised by using appropriate characterisation techniques (temperature programmed desorption and X-ray photoelectron spectroscopy). The kinetic curves of H2<\/sub>O2<\/sub> decomposition were very similar for all the ACs. However, different profiles in the production of \"radical<\/sup>OH radicals were observed. \"radical<\/sup>OH radicals generation seemed to be promoted by low surface oxygen contents. Oxidation of two volatile organic compounds (VOCs) of different polarity, methyl ethyl ketone (MEK) and toluene, pre-adsorbed onto the ACs was finally investigated. H2<\/sub>O2<\/sub> was used as oxidising agent. Both VOCs presented similar maximum oxidation rates, around 70%, in spite of their different hydrophobicity. Some evidences are provided supporting that oxidation of pre-adsorbed VOCs can take place in the inner pore structure of the ACs.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
