Abstract

The four-layer Aurivillius compound BaBi4Ti4O15 is reportedly applied as photocatalyst material with a band
gap energy of 3.2 eV (387.5 nm). As a result, it worksin the ultraviolet light range. The strategy to expand its work function
is to decrease the band gap energy by doped with metal elements like Fe atoms. In this research, we synthesised Fe-doped
BaBi4Ti4O15 (BaBi4Ti3.95Fe0.05O15; BaBi4Ti3.90Fe0.1O15; BaBi4Ti3.85Fe0.15O15; and BaBi4Ti3.80Fe0.2O15) with the purposes to decreases its band gap energy. The diffractogram of samples showed the doped BaBi4Ti4O15 compound was successfully formed and had no impurity phase with space group A21am. Micrograph scanning electron microscopy (SEM) showed plate-like morphology particles and still found agglomeration occurs. The result calculation of Kubelka-Munk showed that Fe doped can decrease the band gap energy of BaBi4Ti4O15.
