Hydrolysis of cellobiose was investigated in the presence of oxidized carbon materials with different textural properties and concentrations of surface acidic groups. Specifically, oxidized microporous activated carbon, graphite-like mesoporous Sibunit carbon, and graphite-like multi-walled carbon nanotubes were studied. Catalytic activity was found to correlate with the concentration of surface acidic sites. Activated carbon oxidized with HNO3 at 130 degrees C exhibited superior catalytic activity due to highest acidity of this material. The catalytic performance was predominantly dependent on acidity, while textural properties only played a minor role, and no mass transfer limitations were observed for microporous catalysts.
