摘要
Metal-deposited polypyrrole (Ppy) exhibiting traits of enhanced conductivities and catalysis has aroused interest in the investigation of metal-Ppy interaction. Recently, a Ppy-based NOx- sensor was found to be interfered with by metal ions such as Ag(I), Cu(II) and Pb(II), hinting at a strong interaction between cations and Ppy. Au(I) was chosen for study because of its possible stronger affinity to Ppy. Results from NMR, cyclic voltammetry (CV) and a scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS) study suggested the existence of the Au(I)-Ppy complex.
