Catalytic behavior of pure carbon materials with different morphology, structure and surface chemistry (catalytic filamentous carbons, nano-diamonds, onion-like carbon, mesoporous graphite-like carbon Sibunit and oxidized samples of Sibunit) towards the catalytic wet air oxidation of phenol were examined. Perceptible but low catalytic activity was registered for all graphite-like carbons, while no activity was exhibited by nano-diamonds. The correlations between catalytic performance of oxidized Sibunit catalysts and methods of oxidative pretreatment and amount of different oxygen-containing species on the carbon surface were evaluated. The conclusion about the key role of transition metal impurities in carbon catalysts was made.
