摘要: 本文研究了纳米银(AgNPs)在氨基注入氧化铟锡(ITO)薄膜表面的吸附. 通过氨基注入的方法得到了氨基功能化的ITO表面(NH2/ITO), 并将纳米银直接吸附在NH2/ITO上得到纳米银修饰NH2/ITO基体(AgNPs/NH2/ITO). 使用傅里叶红外光谱、X射线光电子能谱、原子力显微镜、扫描电镜、紫外可见光谱和电化学方法对AgNPs/NH2/ITO制备过程进行了表征. 结果显示纳米银可在NH2/ITO表面高密度地吸附, 并且纳米银有良好的电化学活性. 这种不借助于有机连接分子吸附纳米银的方法为制备纳米银修饰材料提供了新的选择.

Abstract: An effective approach to attach silver nanoparticles (AgNPs) directly onto an indium tin oxide (ITO) surface with high density was reported. An NH2+ ion implanted ITO (NH2/ITO) film was prepared and the AgNPs were adsorbed onto the surface of the obtained NH2/ITO film resulting in an AgNPs-attached NH2/ITO (AgNPs/NH2/ITO) substrate. Characterization of stepwise changes in the ITO, NH2/ITO, and AgNPs/NH2/ITO surfaces were carried out using Fourier transform infrared (FT-IR) spectrometry, X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), scanning electron microscopy (SEM), ultravioletvisible (UV-Vis) spectroscopy, and electrochemical methods. Cyclic voltammtric voltammetry results indicate that the immobilized AgNPs on the NH2/ITO electrode gave excellent electrochemical properties, implying facile electrochemical communication between the AgNPs and the ITO substrate through theby implanted amino groups. Thus, the AgNPs/NH2/ITO surfaces are promising as new functional interfaces because AgNPs can be attached to surfaces without the use of organic binding molecules.
