Synthesis and Characterization of Lanthanum Ferrites and Their Photocatalytic Studies

Abstract

In this fast growing environmental friendly research world, development of highly efficient, non-toxic photocatalyst for potential applications is required. Herein, a strong ability photocatalyst Lanthanum Ferrite (LF) was synthesized by solution combustion synthesis using Coconut oil (LFC) and Urea (LFU) as fuel. X-ray results indicate the development of pure phase for LF NP of perovskite structure in both the fuels having crystal size in the range of 24-48 nm. FTIR results reveal that the functional groups were confirmed. The energy band gap value from UV DRS studies was suitable for the photocatalytic degradation under visible light. The NPs displays excellent photocatalytic degradation activity for Reactive Blue 4 (RB4) dye under UV & Visible light within 120 mins resulted 75% and 84% by LFU, 89% and 98% by LFC photocatalyst respectively. LF photocatalyst has very good stability confirmed recyclability experiment for 5 cycles.
