AbstractLarge-mesoporous Al2O3 has been successfully synthesized from calcined coal-series kaolin by using cetyltrimethylammonium bromide(CTAB) as template at room temperature. After calcined at 700 degrees C, the as-synthesized samples have transformed to mesoporous gamma-Al2O3. The mesoporous gamma-Al2O3 has a specific area of 253.4 m(2) g(-1), large pore volume of 1.487 cm(3) g(-1), and an average pore diameter of 12.9 nm. TEM images show that the calcined mesoporous alumina has wormhole-like pores without long-range ordered framework. A probable formation mechanism of large-mesoporous gamma-Al2O3 is also proposed.
