Fabrication and adsorption properties of hybrid material with micropores from SBA-15

Abstract

A novel hybrid material with microporous structure was fabricated from SBA-15 with mesopores via silane modification and hydrolysis. Two kinds of pores with diameters of 6.5 and 1.9 nm were found in the hybrid material. Compared to that of SBA-15, the surface area of the hybrid material increased from 395.9 m²/g to 667.4 m²/g while its porous volume decreased. The new hybrid material was found to have high efficiency in removing NaCl from solution, and the maximum adsorption capacity of it was ca. 517.5 mg/g.
