基于纳米氧化锌-还原氧化石墨烯的分子印迹光电化学传感器测定土霉素OA北大核心CSTPCD
Zinc Oxide-Reduced Graphene Oxide-based Photoelectrochemical Sensor Combined with Molecularly Imprinting Technique for Sensitive Detection of Oxytetracycline
利用水热法合成了纳米氧化锌-还原氧化石墨烯(rGO)复合材料,采用傅里叶变换红外光谱、X射线衍射和X射线光电子能谱确定此复合材料的价态结构.以ZnO-rGO作为光电化学传感器的光电转换材料,以土霉素(OTC)为模板分子,通过电聚合OTC和吡咯(Py)的方法构建分子印迹光电化学传感器.将聚吡咯(PPy)膜中的OTC洗脱后,在PPy膜中留下OTC的特异性"印迹孔穴",从而可对OTC选择性识别.在优化的条件下,此传感器的光电流变化值与OTC浓度(0.1…查看全部>>
In this work,zinc oxide-reduced graphene oxide(ZnO-rGO)nanocomposites were fabricated using hydrothermal method,and the chemical and physical properties of the synthesized ZnO-rGO were characterized by several techniques,including X-ray diffraction and Fourier transform infrared(FT-IR)spectroscopy.A molecularly imprinted photoelectrochemical sensor based on ZnO-rGO was designed for sensitive detection of oxytetracycline(OTC).Polypyrrole(PPy)film was electrop…查看全部>>
