Double-GrN remarkably enhanced the catalytic efficiency for O2 dissociation reactions and accelerates the generation of highly chemically reactive oxygen functional groups. The promotion effect is ascribed to the reduction of the work function of carbocatalysts due to N doping, which facilitates the transfer of electrons from carbocatalysts to the adsorbed O2 molecules for their activation.

The intact activated carbon CAN-8, obtained from nutshells by activation with water vapours, in the presence of oxygen and at relatively low temperatures, possesses catalytic activity, caused by the presence of alkaline functional groups on its surface, as well as by the formation, in these experimental conditions, of the OH radical, which has a high oxidation potential. After 25 cycles of the process of methylene blue oxidation, the data of chromatographic analyses indicate the presence of three organic components in the solution.
