The Preparation of Boron-doped Activated Alumina by impregnating boron in the period of boehmite

This paper systematically studied the pore structure, crystal phase, surface acidity and the chemical environment of aluminum of boron-doped γ-alumina, by impregnating boron in the period of boehmite. The nitrogen adsorption, XRD, FTIR etc. technique was used to determine the pore texture, crystallography, acid/base properties and aluminum coordination. the XRD spectrum of boria-alumina have no significant change due to the addition of boron. The specific surface area and pore volume diameter of B-Al2O3 increase significantly. The NMR spectra of B-Al2O3 shows that boron changed the chemical environment of aluminum, which caused differences in the physical and chemical properties of the surface.
