Metal-modulated growth of Au nanoparticles by electropolymerized 8-hydroxyquinoline films

摘要：

　　8-hydroxyquinoline (8-Hq) films were electropolymerized on indium-fin-oxide-coated (ITO) glass slides by using cyclic voltammetry.The 8-Hq electropolymerized on ITO electrode (8-Hq/ITO) was immersed in a 5-mL solution containing 0.01 M phosphate buffer solution (PBS,pH 7.0),0.8 mM cetyltfimethylammonium chloride,20 μL of HAuCl4 (1%,w/w),and 50 tL of Au nanoparticle seeds.The mixture was incubated at 57℃ for 3 h.Then Au nanoparticles were grown and deposited onto the 8-Hq/ITO electrode.It was found that some metal ions (Zn2+,Cd2+,Mg2+,and Pb2+) could inhibit the growth of Au nanoparticles.The metal-modulated growth of Au nanoparticles was studied by UV-vis spectra and differential pulse voltammetry.
