Kinetic comparison between ferric ion and decamethyferrocene at the liquid/liquid interface as studied by scanning electrochemical microscopy
摘要:
Comparison in electron transfer (ET) processes from decamethyferrocene (DMFe) in nitrobenzene (NB) to ferric ion in aqueous phase was investigated for the first time by the scanning electrochemical microscopy (SECM). As compared with the system of Fe(CN)63--DMFe, the ET rate obtained from Fe3+-DMFe was lower in spite of larger driving force, which may arise from the effect of reorganization energy. Otherwise, the effect of common ion on rate constants was also probed and results suggested additional complexity of the ET mechanism between Fe(CN)63-and DMFe.
