Abstract:Using TiO2 and La2O3-doped TiO2 as supports,which were prepared by the sol-gel method,a series of Au catalysts were prepared by the deposition-precipitation method. Their catalytic performance for selective hydrogenation of cinnamaldehyde was tested and their physical and chemical properties were investigated by the techniques of N2 adsorption-desorption,X-ray diffraction,high-resolution trans-mission electron microscopy,temperature-programmed reduction,and X-ray photoelectron spectroscopy. The results show...
