The catalytic activity of carbon nanoporous materials of SCN and KAU type, their oxidized and nitrogen-containing modified forms, enzyme catalase in the model reaction of benzoyl peroxide decomposition in ethyl acetate solutions are determined by the calculation of the Michaelis constants according to the kinetics of substrate decomposition. It is found that the catalytic activity of studied samples correlates with surface basicity and the presence of quaternary nitrogen groups in the structure. The doping by nitrogen and oxygen heteroatoms increases and decreases, respectively, their catalytic activity.
