Morphological and chemical features of nano and macroscale carbons affecting hydrogen peroxide decomposition in aqueous media

► Detailed study of the decomposition of hydrogen peroxide on nano and microforms of carbons. ► Doping of nano or microforms of carbons increases the reaction rate, but only for a limited number of reaction cycles. ► SLGO and pure CNT exhibit greater stability in their performance over subsequent cycles compared with other carbons. ► Incremental function distribution analysis of the reaction rate offers deep insight to material performance.
