基于多金属氧酸盐和多壁碳纳米管的双酚A电化学传感器的构建与性质(英文)
Construction and Properties of the Electrochemical Bisphenol A Sensor Based on Polyoxometalates and Multi-walled Carbon Nanotubes
【摘要】 选择含N配体(L=1,3-双(1-咪唑)丙烷)与磷钼酸(H3PMo12O40)水热合成了一个新的无机-有机杂化化合物(H2L)2(HL)2L(PMo12O40)2·2H2O (PMo12)。通过红外、热重、X射线光电子能谱、X射线粉末衍射和单晶衍射等对该化合物进行了表征。X射线单晶衍射表明该化合物为3D结构。将该化合物和多壁碳纳米管修饰在玻碳电极上构造了一种双酚A电化学传感器并对其传感性能进行研究。研究表明,在1~20μmol·L-1范围内,检出限为0.5μmol·L-1(S/N=3),并且该传感器具有良好的抗干扰和稳定性。
【Abstract】 A new inorganic-organic hybrid(H2L)2(HL)2L(PMo12O40)2·2H2O(marked as PMo12) derived from the self-assembling of N-containing ligands L(L=1, 3-bis(1-imidazolyl) propane) and inorganic polyoxometalates(H3PMo12O40) have been hydrothermally synthesized. The compound was characterized by infrared spectroscopy(IR),thermal gravity(TG), X-ray photoelectron spectroscopy(XPS), X-ray diffraction(XRD), and single-crystal X-ray diffraction. Studies on single-crystal X-ray diffraction reveal that the compound displays 3D structures. Then a bisphenol A(BPA) electrochemical sensor based on PMo12 and multi-walled carbon nanotubes(MWCNTs) has been successfully constructed. The detection limit was 0.5 μmol·L-1(S/N=3) in a range of 1-20 μmol·L-1, and the sensor had good anti-interference and stability. CCDC: 1054587, PMo12.
