The influence of hydrochloric acid on the features of SBA-15 particles

Abstract

The template method synthesis of both SBA-15 materials with elongated and spherical particles was performed using a surfactant Pluronic P123. The HCl (p.a.) was used to synthesize material with elongated particles connected in chain structures grouped into shapes resembling sheaves of wheat. In the synthesis of spherical SBA-15 with diameters ranging from 0.5 to 2 μm, a spent HCl solution which was obtained after chemical treatment of clay was used where the dominant presence of the spheres was confirmed by the SEM method. In addition to the methods mentioned above, XRD, EDS and FTIR methods characterize SBA-15 materials.
