Abstract: POAP-Cu~+ is a good electrocatalyst for the reduction of O_2 into H_2O_2. It was found that Cu~(2+) can incorporate into POAP and form a stable POAP-Cu~+ film, which evidently electrocatalyzes the reduction of O_2 to produce H_2O_2. The rate constant of this reduction(k) is 4.33·10~2 (L·mol~(-1)·s~(-1)).

Key words: Poly-ortho-aminophenol(POAP), Incorporation, Electrocatalysis
