Synthesis and photocatalytic property of bismuth titanate Bi4Ti3O12

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 photocatalystic activities to photodegrade 10 ppm methyl orange solution in 4 h under UV irradiation.
