One of interesting properties of Bi 4 Ti 3 O 12 is photocatalyst. The band gap of Bi 4 Ti 3 O 12 is 2.9 eV as results only work at ultraviolet wavelength range. Metal doped to Bi 4 Ti 3 O 12 can reduce band gap energy. In this work, Bi 4 Ti 3 O 12 was doped vanadium (Bi 4 Ti 3- x V x O 12 with x = 0.05; 0.1; 0.15; 0.2) using solid state reaction method. X-ray diffraction data show that Bi 4 Ti 3- x V x O 12 ( x = 0.05; 0.1; 0.15; 0.2) were successfully formed with space group B2cb, however there is small impurities of VO 2 phase. Scanning electron microscopy (SEM) images showed that the particle of all obtained Bi 4 Ti 3- x V x O 12 ( x = 0.05; 0.1; 0.15; 0.2) have shape platelet-like. Diffuse Reflectance Spectroscopy data showed that the energy band gap of Bi 4 Ti 3- x V x O 12 decreased by increasing vanadium dopant.
