Abstract

One of interesting properties of Bi4Ti3O12 is photocatalyst. The band gap of Bi4Ti3O12 is 2.9 eV as results only work at ultraviolet wavelength range. Metal doped to Bi4Ti3O12 can reduce band gap energy. In this work, Bi4Ti3O12 was doped vanadium (Bi4Ti3-xVxO12 with x= 0.05; 0.1; 0.15; 0.2) using solid state reaction method. X-ray diffraction data show that Bi4Ti3-xVxO12 (x= 0.05; 0.1; 0.15; 0.2) were successfully formed with space group B2cb, however there is small impurities of VO2 phase. Scanning electron microscopy (SEM) images showed that the particle of all obtained Bi4Ti3-xVxO12 (x= 0.05; 0.1; 0.15; 0.2) have shape platelet-like. Diffuse Reflectance Spectroscopy data showed that the energy band gap of Bi4Ti3-xVxO12 decreased by increasing vanadium dopant.
