摘要 以SiO2和纳米Au颗粒为原料,采用自组装方法合成了负载型金催化剂。应用傅立叶变换红外光谱(FT-IR)、X射线能谱(EDS)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)及原子吸收光谱(AAS)等对样品进行了表征。将该催化剂用于空气氧化环己烷反应的实验结果显示,其不仅具有较高的催化活性和稳定性,而且经简单处理即可重复使用多次。 Supported gold catalyst was prepared by self-assembly method, using SiO2 and Au nano-particles as the reactants. Fourier transform infrared spectroscopy (FT-IR), X-ray energy dispersive spectrometer (EDS), trans- mission election microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and atom absorption spectrometry (AAS) were used to characterize the samples. The catalyst was applied for cyclohexane oxidation with air and the re- suits showed high catalytic activity and stability of it. Moreover, the catalyst can be used repeatedly for at least four times after easy treatment.
