摘要：

This study prepared layered perovskite Bi4Ti3O12 crystals by CSD method, and examined the photocatalystic property of Bi4Ti3O12 crystals for. photo-degradation of methyl orange. The crystal particulate of Bi4Ti3O12 crystals was observed to be in spherical shapes with diameters of 10-90 nm from TEM images. The Bi4Ti3O12 catalyst shows high photocatalytic activities to photodegrade 10 ppm methyl orange solution in 4 h under UV irradiation. (C) 2002 Elsevier Science B.V. All rights reserved.
