电沉积制备ZnO纳米棒修饰电极上氧化还原蛋白的电化学行为
Electrochemical Behavior of Redox Proteins on ZnO Nanorod-Modified Electrodes Prepared by Electrodeposition
摘要
Abstract
We successfully prepared ZnO nanorod-modified Au (ZnO nanorod/Au) electrodes using one-step cathodic electrodeposition.Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the morphology and crystal phase of the ZnO nanorods.The data showed that the ZnO nanorods were wurtzite type crystals with a hexagonal rod shape and a diameter of about 100 nm and that the ZnO nanorods were arranged well on the surface of electrodes.These ZnO nanorod-modified electrodes were able to detect direct electron transfer from cytochrome c (cyt c).Cyclic voltammograms showed that the direct electron transfer of cyt c with heme iron in different valence states was easily achieved by the ZnO nanorod/Au electrode.Data of amperometric responses demonstrated that a linear amperometric response to hydrogen peroxide was observed on the ZnO nanorod/Au electrodes after adsorbing cyt c.关键词
