Enhancing the production of hydrogen peroxide from electrocatalytic oxygen reduction reaction by tailoring the electronic states of single-walled carbon nanotubes: a synergistic effect from interior filling and exterior oxidation

Abstract

Single-walled carbon nanotubes co-modified with interior filling of phosphomolybdic acid and successive exterior oxidation (O-HPMO@SWCNTs) possess better two-electron oxygen reduction reaction performance than the HPMO-filled SWCNTs, oxidized SWCNTs or pristine SWCNTs.
