Abstract

SrBi4Ti4O15 is one of the four-layered Aurivillius compounds that can be used as photocatalyst material. Expanding its work function under a wider wavelength can be conducted by introducing a metal dopant into SrBi4Ti4O15 in view of its reduced band gap energy. In this research, vanadium doped SrBi4Ti4O15 (SrBi4Ti4-nVnO15 (n= 0, 0.05, 0.1, and 0.15)) was synthesized via molten KCl salt method. The diffractogram showed that the SrBi4Ti4-nVnO15 compounds (n= 0, 0.05, 0.1, and 0.15) were successfully crystallized in space group A21am without any impurities. The SEM micrographs confirmed the plate-like morphology of SrBi4Ti4-nVnO15 (n= 0, 0.05, 0.1, and 0.15) and the calculation of the Kubelka-Munk function on the UV-Vis DRS spectra showed that the vanadium effectively reduced the band gap energy value from 3.04 eV (408 nm) to 2.84 eV (437 nm)
