Abstract
Mesoporous nanocrystalline anatase was prepared via EISA employing P123 and CTAB as structure directing agents. The resultant mesoporous crystalline phases exhibited specific surface areas as high as â¼150Â m2Â gâ1, average unimodal pore sizes of â¼3Â nm and â¼6Â nm, and average crystallite size of â¼10Â nm; and were used as photocatalysts for the UV degradation of methylene blue, methyl orange, methyl red and rhodamine 6G. The mesoporous anatase phases photodegraded MB, MO and MR â¼2-3 times faster than conventional nanocrystalline anatase and showed limited photocatalytic activity for rhodamine 6G.
