Description:
Materials, Vol. 10, Pages 886: Microwave-Assisted Pillaring of a Montmorillonite with Al-Polycations in Concentrated Media Materials doi: 10.3390/ma10080886 Authors: Beatriz González Alba Pérez Raquel Trujillano Antonio Gil Miguel Vicente A montmorillonite has been intercalated with Al3+ polycations, using concentrated solutions and clay mineral dispersions. The reaction has been assisted by microwave radiation, yielding new intercalated solids and leading to Al-pillared solids after their calcination at 500 °C. The solids were characterized by elemental chemical analysis, X-ray diffraction, FTIR spectroscopy, thermal analyses, and nitrogen adsorption. The evolution of the properties of the materials was discussed as a function of the preparation conditions. Microwave treatment for 2.5 min provided correctly pillared solids.
