Porous clay heterostructures with enhanced acidity obtained from acid-activated clays.
Porous clay heterostructures (PCHs) with enhanced acidity may be prepared from suitably acid-activated montmorillonite clays; the higher acidity arises from Brønsted acid sites generated by acid treatment of the clay prior to its use as a host for PCH formation.
