The common characterization of nano-size gold catalysts is analyzed from four aspects including Transmission Electron Microscopy(TEM),X-ray Diffraction(XRD),X-ray Electron Spectroscopy,and Infrared Spectroscopy(IR).The effects on the above techniques on charactering the particle and crystal size of gold,detecting the valence state and electronic environment of gold,analyzing the surface absorption of CO molecule onto gold are analyzed in detail.The potential significance of the Density functional theory(DFT) calculation over investigation on reaction mechanism is also prospected.
