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=4.33×10~2L·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.
POAP-Cu^+ is a good electrocatalyst for the reduction of O_2 into H_2O_2.It wasfound that Cu^(2+)can incorporate into POAP and form a stable POAP-Cu^+ film,whichevidently electrocatalyzes the reduction of O_2 to produce H_2O_2.The rate constant ofthis reduction(k)is 4.33·10~2(L·mol^(-1)·s^(-1)).
