Chemical modification (CM) and deposition-precipitation (DP) methods were used for the dispersion of active Au nanoparticles on mesoporous silica materials in this work. XRD, TEM, N 2 adsorption isotherms and UV-Vis absorption spectra were used to characterize in detail Au-SBA-15 materials prepared by the two methods. The analysis results showed that high loading (1.7%, by mass) and uniform...
