Synthesis, characterization of SO42-/Al-MCM-41 mesoporous molecular

Xing Fenglan

Abstract

The mesoporous molecular sieves Al-MCM-41 is synthesized under hydrothermal condition using cetyl trimethyl ammonium bromide(CTAB) surfactants as template,tetraetylorthosilicate(TEOS)as silicic,sodium aluminate as aluminum source,according to the ratio of Si:Al =50:1.0.SO42-/Al-MCM-41 mesoporous molecular sieves was obtained with sulfuric acid by infusing.Al-MCM-41 and SO42-/Al-MCM-41 are characterized by power X-ray diffraction(XRD),nitrogen adsorption and Hammett measurements.
