摘要
An electron donor-acceptor linked supramolecular system composed of polyhydroquinone (PH(2)Q) and fullerene (C-60) was prepared and characterized by different techniques like TEM, UV-vis, XRD and photo electrochemical photocurrent detection techniques. The photoelectrochemical properties of nitric oxide (NO) were first investigated. An enhanced cathodic photocurrent response was obtained on the PH(2)Q C-60 modified ITO electrode under visible light radiation with NO as electron acceptor. The photoelectrochemical process of NO was discussed and a novel photoelectrochemical sensor of NO was developed. The influence of the main interferents, especially the significant interfering species NO2- was proved to be negligible. The photoelectrochemistry of NO and the new NO sensor may have potential applications in photoelectrochemistry and biological analysis field. (C) 2016 Elsevier B.V. All rights reserved.
