Highly selective hydrogen peroxide electrosynthesis on copper phthalocyanine: interface engineering with an azo-polymer

The electrode–electrolyte interface was adjusted by azo molecule modification to improve the desorption of HO 2 − . The H 2 O 2 selectivity and stability of CuPc-TAP-F in a wide potential window is a higher level in the field of H 2 O 2 electrosynthesis.
