Catalytic wet peroxide oxidation (CWPO) is regarded as a potential solution for the treatment of aqueous effluents containing recalcitrant and toxic organic pollutants, difficult to remove by conventional biological processes, mainly if present at high concentrations (1-10 g L-1) [1]. In a recent study, three magnetic carbon nanotube (CNT) samples, named E30 (undoped), A30 (completely N-doped) and E10A20 (partially N-doped), were synthesized by chemical vapor deposition and tested in the CWPO process, finding that N-doped hydrophilic surfaces promoted the fast decomposition of H2O2 into nonreactive species (H2O and O2), hindering CWPO [2].
