文献摘要

A ternary composite of poly (3,4-ethylenedioxythiophene)/gold/graphene (PEDOT/Au/GO) for promising electrochemical sensor was synthesized by solid-state heating method. The interaction between the PEDOT, Au, and GO explored for detection of nitrite and iodate. It was found that the PEDOT/Au/GO composite had shale-like morphology with a uniform distribution of gold nanoparticles. Electrochemical experiments showed that the PEDOT/Au/GO composite modified electrode exhibited good electrocatalytic activity toward determination of iodate. The amperometric experiments at the PEDOT/Au/GO/GCE revealed that a good linear relationship existed between peak current and the concentration in the range of 100–1000 μM with the detection of 0.53 and 0.62 μM (S/N = 3) for nitrite and iodate, respectively. Moreover, the current response of PEDOT/Au/GO/GCE for nitrite and iodate at 10 μM was up to 9.59 and 11.47 μA, respectively. Mechanisms of the direct electron transfer between ion(nitrite or iodate)and the PEDOT/Au/GO composite
通过固态加热法合成了一种用于有前景的电化学传感器的聚(3,4 - 乙烯二氧噻吩)/金/石墨烯(PEDOT/Au/GO)三元复合材料。探索了PEDOT、Au和GO之间的相互作用以用于检测亚硝酸盐和碘酸盐。发现PEDOT/Au/GO复合材料具有页岩状形态,金纳米粒子分布均匀。电化学实验表明,PEDOT/Au/GO复合材料修饰电极对碘酸盐的测定表现出良好的电催化活性。在PEDOT/Au/GO/玻碳电极(GCE)上进行的安培实验显示,在100 - 1000 μM范围内,峰电流与浓度之间存在良好的线性关系,亚硝酸盐和碘酸盐的检测限分别为0.53和0.62 μM(信噪比 = 3)。此外,PEDOT/Au/GO/玻碳电极对10 μM亚硝酸盐和碘酸盐的电流响应分别高达9.59和11.47 μA。 离子(亚硝酸盐或碘酸盐)与PEDOT/Au/GO复合材料之间直接电子转移的机制
