Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles are formed from the calcination of non-porous CPPs.

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, ...

Al,Fe-pillared clay was synthesized from domestic clay from Bogovina according to a common procedure: grinding, sieving, Na exchange, pillaring, drying and calcination. Two synthesized samples differing only in calcining conditions were prepared. Phase composition and textural properties of the starting clay and synthesized pillared clays were characterized using X-ray diffraction and physisorp...

Co3O4 catalysts were prepared via carbonate precipitation and subsequent calcination under specific conditions. The different characterized as received using several techniques tested in the total oxidation of toluene or propane. Calcination at low temperature dynamic conditions resulted with small crystallite sizes large surface areas. performances appeared to be closely related low-temperatur...
