摘要: Cu~(2+)可嵌入聚邻氨基酚(POAP)膜中形成POAP-Cu~+膜, POAP-Cu~+膜电极对O_2还原具有明显的电催化作用, 电催化活性中心是Cu~+, O_2还原经过H_2O_2步骤, 反应速率常数k=4.33×10~2 L·mol~(-1)·s~(-1). POAP-Cu~+膜电极是使O_2还原成H_2O_2的良好催化剂.

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)).
