摘要
应用微机联用四电极恒电位测试系统研究FeCP_2(NB)/Fe^(3+)(W)在水(W)/硝基苯(NB)界面发生的电子传递以及四苯卟啉及其第一过渡金属配合物(MTPP)对上述电子迁移过程的影响。结果表明,对W/NB界面体系,FeCP_2(NB)被Fe^(3+)(W)的氧化表现为可逆单电子迁移,其微观反应历程预想属复相电子迁移机理,H_2TPP对上述体系不起促进作用,而各MTPP则表现出不同程度的影响,其中,MnTPP与NiTPP促进作用最显著,FeClTPP作用微弱,CuTPP、ZnTPP、CoTPP却反有抑制作用。
The effects of tetraphenylporphyrin (H2TPP) and metallo-tetraphenylporphyrin coordination compounds (MTPP, M = Mn, FeCl, Co, Ni, Cu, Zn ) on electron transfer between FeCP2 (NB) and Fe3+(W) at water(W)/nitrobenzene(,NB) interface were investigated. The results showed that the reaction of FeCP2(NB) oxidized by Fe3+ (W) ion at interface was reversible with respect to one electron transport, and its microscopic mechanism was considered as heterogenous electron transport. H2TPP showed no assisting effect on the interface electron transfer between FeCP2 (NB) and Fe3+ (W); But MTPP showed different assisting effects, in which MnTPP and NiTPP showed significant, FeClTPP was weak, CoTPP, CuTPP and ZnTPP had inhibition in stead.
