Triton X-100 directed synthesis of mesoporous γ-Al2O3 from coal-series kaolin
Source abstract
Abstract
Mesoporous gamma-Al2O3 has been successfully synthesized by using calcined coal-series kaolin as raw material and Triton X-100 (TX-100) as template. The effect of TX-100/Al3+ ratio on the structural and textural properties of mesoporous gamma-Al2O3 was investigated. Physical properties of obtained samples were characterized by X-ray diffraction (XRD), N-2 adsorption-desorption, transmission electron microscopy (TEM), thermogravimetric analysis (TG), scanning electron microscopy (SEM) with energy-dispersive X-ray analysis (EDAX) and Fourier transform infrared spectroscopy (FTIR). The results indicated that the amount of TX-100 influenced the structure and porous properties of mesoporous gamma-Al2O3 significantly. When TX-100/Al3+ ratio was in the range of 0.03-0.15, all samples had mesoporous structures with BET surface area of 193.0-261.0 m(2)/g and pore size of 5.04-6.71 nm. In addition, the reaction mechanism involved in the process was proposed and discussed. (C) 2013 Elsevier B.V. All rights reserved.
