Abstract

Bi4Ti3O12 is one of member threelayer Aurivillius compound family, which has the potential as a photocatalyst material with band gap energy 2.9 eV (427 nm). Therefore, to expand its utilization, the gap energy must be reduced. Doping with metal is one technique that can reduce the energy of a band gap. In this study, we synthesized vanadium doped Bi4Ti3O12 (Bi4Ti3-xVxO12 (x = 0, 0.05; 0.1; 0.15 and 0.2) by molten salt synthesis. Difractogram data shows that the Bi4Ti3O12 phase is formed with BiNaO3 and NaV6O11 impurities. The image of SEM showed that the particle shape of Bi4Ti3O12 is plate like. UV-Vis DRS spectra showed that the vanadium doped Bi4Ti3O12 have lower band gap energy than Bi4Ti3O12.
