    Abstract

    A method by modifying tetraethyl orthosilicate (TEOS) with nickel species has been developed for the synthesis of mesoporous silica with high nickel content (up to 14.7 wt% of Ni). Using the method, nickel-containing mesoporous materials were obtained with high BET surface area and pore volume. The materials were characterized by means of X-ray powder diffraction, transmission electron microscopy, energy dispersive X-ray spectroscopy, N2 adsorption, Fourier transform infrared. Nickel species were incorporated into the silica frameworks. Formation of nickel phyllosilicates was also confirmed. After activation, mesostructures are still intact. Small nickel clusters embedded in the silica walls were found.
