Abstract

An aurivillius phase Layered perovskite Bi₅FeTi ₃O₁₅ system was synthesized for first time by the solid-state reaction method yielding a single phase Bi₅FeTi ₃O₁₅ at only 1030°C. The electronic band structure and optical properties as well as the crystallization behavior of the materials were studied by using UV-DRS and XRD. The as-prepared particles those were the agglomerates of 25 nm crystals, exhibited the band gap of 2.38 eV (525 nm). Their visible light (λ ≥ 420 nm) photocatalytic activity as studied by the photo-decomposition of isopropyl alcohol (IPA) was found to be much higher than that of well-known TiO_2-xN_x photocatalyst.
