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.
Cu 2+ can be embedded into poly-o-aminophenol (POAP) film to form POAP-Cu ~ + film. POAP-Cu ~ + film electrode has obvious electrocatalysis for O_2 reduction. The electrocatalytic activity center is Cu ~ + , The reaction rate constant k = 4.33 × 10 -2 L · mol -1 (-1) · s -1 after O_2 reduction through H_2O_2 · POAP-Cu ~ + membrane electrode is a good catalyst for reducing O_2 to H_2O_2.
