采用一种简单的方法制备了氧化石墨烯包覆多壁碳纳米管（GO@MWNTs）的纳米复合材料。该复合物具有良好的分散性。在GO@MWNTs上非共价组装了一种反芳香族二苯甲酰基取代的镍（II）去甲可咯配合物（NiNC），形成了一种新的三元杂化物（GO@MWNTs-NiNC）.采用原子力显微镜、透射电镜、紫外-可见光谱、红外光谱和热重分析等分析技术对杂化材料进行了表征。基于该三元杂化物对多巴胺（DA）的优良电催化性能，提出了一种新的选择性、灵敏测定DA的电化学传感平台。在优化的条件下，测定DA的线性范围为0.03 ~ 80 μ M，检出限为0.012 μ M（S/N = 3）。该传感器具有良好的稳定性、选择性和重现性。(C)2016爱思唯尔有限公司版权所有
A nanocomposite of graphene oxide encapsulated multiwalled carbon nanotubes (GO@MWNTs) was produced by a simple method. The composite displayed good dispersibility. An antiaromatic dimesity-substituted nickel (II) norcorrole complex (NiNC) was noncovalently assembled on the GO@MWNTs to form a novel triad hybrid (GO@MWNTs-NiNC). The hybrid was characterized by different analytical techniques containing AFM, TEM, UV-vis spectroscopy, FT-IR spectroscopy, and TGA. Based on the excellent electrocatalytic properties of the triad hybrid towards dopamine (DA), a new electrochemical sensing platform for the selective and sensitive determination of DA was proposed. Under optimized conditions, the linear response range for determining DA were obtained over the range of 0.03-80 mu M with the estimated detection limit of 0.012 mu M (S/N = 3). The fabricated sensor also exhibits such features as good stability, selectivity, and reproducibility. (C) 2016 Elsevier Ltd. All rights reserved.
