中文摘要：采用化学氧化法合成了聚乙烯亚胺-联吡啶钌@二氧化硅-金@铂(PEI-Ru@SiO2-Au@Pt)发光功能化纳米复合材料;构建灵敏稳定的响应界面,制备了精准高效的固相增强型电化学发光纳米复合材料.通过透射电子显微镜(TEM)、紫外-可见吸收光谱(UV-Vis)、傅里叶变换红外光谱(FTIR)、电化学阻抗谱(EIS)、循环伏安法(CV)和双电位阶跃法对合成的纳米复合材料进行了表征和性能测试.研究了PEI-Ru@SiO2-Au@Pt纳米复合材料的形貌和结构以及电化学发光性能(ECL).结果表明:PEI-Ru@SiO2-Au@Pt纳米复合材料具有优异ECL性能,加入Au@Pt后,PEI-Ru@SiO2-Au@Pt纳米复合材料的ECL强度是PEI-Ru@SiO2的5倍.

外文标题：Preparation of PEI-Ru@SiO2-Au@Pt Composites and Electrochemical Luminescence Properties

外文摘要：Polyethyleneimine-bipyridine ruthenium@silicon dioxide-Au@Pt (PEI-Ru@SiO2-Au@Pt) luminescent functionalized nanocomposites were synthesized by chemical oxidation method; sensitive and stable responsive interfaces were constructed for the preparation of precise and efficient solid-phase enhanced electrochemical luminescent nanocomposites. The synthesized nanocomposites were characterized and tested by transmission electron microscopy (TEM), ultraviolet-visible absorption spectroscopy (UV-Vis), Fourier transform infrared spectrometer (FTIR), electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and two-potential step method. The morphology and structure as well as electrochemiluminescence properties (ECL) of PEI-Ru@SiO2-Au@Pt nanocomposites were investigated. The results showed that the PEI-Ru@SiO2-Au@Pt nanocomposites had excellent ECL properties. After the addition of Au@Pt, the strength of the ECL of the PEI-Ru@SiO2-Au@Pt nanocomposites was five times higher than that of PEI-Ru@SiO2.
