Abstract

Hexagonally ordered mesoporous silica SBA-15 was successfully synthesized for the first time using natural clay from low-grade potash ores of a salt lake in Qinghai, China, without addition of silica reagents. The influence of changes in processing parameters, such as activation method, hydrothermal conditions, and calcinations temperature, on the textural characteristics of the SBA-15 products was studied. A pretreatment process involving iron-removing and alkali fusion was critical to the successful use of natural clay from low-grade potash ores as a source of silica in the surfactant-templated hydrothermal synthesis of SBA-15. The product was characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), N2 adsorption/ desorption isotherms, transmission electron microscopy (TEM) and TG-DSC analysis. The resulting mesophase had a surface area of 546.6m2.g-1 and an average pore diameter of 6.2 nm with narrow pore size distribution. The results indicated that salt lake clay was a promising low-cost precursor for the production of mesoporous molecular sieve.
