Aurivillius phase layered perovskites Bi6Ti3WO18 was prepared by the sol-gel citrate-complexation synthesis. The sample developed into the plate-like nanoparticles with the exposed (001) facets. The phase formation and structure have been verified via X-ray polycrystalline powder diffraction (XRD) Rietveld refinements. The nanoparticles were investigated via the measurements such as FE-SEM, TEM, EDS, and the surface analyses. UV-Vis absorption data revealed that the Aurivillius compound has a direct band characteristic with the band energy of 2.214 eV. The band structure of Bi6Ti3WO18 nanoparticles was discussed on the base of the experiments and theoretical calculation. Bi3+-containing Aurivillius Bi6Ti3WO18 shows efficient photocatalytic degradation for rhodamine B dye (RhB) with the visible light irradiation (lambda > 420 nm). Dynamic characteristic of the light-created excitons was measured by the luminescence and decay lifetime. The multivalent properties of W and Ti ions in the Aurivillius-like lattices of Bi6Ti3WO18 photocatalyst were discussed.
