The electrochemical reactions of carboxylic and lactone groups on carbon nano‐onions (CNOs) in aqueous solutions result in non‐Kolbe products: alcohols, ketones, ethers and epoxides. The anodic/cathodic conversion of ox‐CNOs was assessed by Boehm titrations and by Raman and DRIFTS‐FTIR (diffuse reflectance infrared Fourier transform spectroscopy). The electrochemical properties of oxidized carbon nano‐onions were investigated by cyclic voltammetry in aqueous solutions. The ox‐CNOs are electrochemically active as a result of the reduction of the oxygen‐containing groups.
