Microwave-Assisted Pillaring of a Montmorillonite with Al-Polycations in Concentrated Media

Microwave-Assisted Pillaring of a Montmorillonite with Al-Polycations in Concentrated Media

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 chara...
