Structural, optical and photocatalytic activity of cerium titanium ferrite

Perovskite phase Cerium Titanium Ferrites (CeTi1-xFexO3-δ) are prepared via sol-gel route, by varying mole ratios (X = 0, 0.5 & 1.0) and the synthesized nanocatalysts used for the degradation of Methylene Blue organic pollutant. The as synthesized photo catalysts (CTFO-1, CTFO-2 and CTFO-3) were characterized using UV-vis, FT-IR, TG-DTA, PXRD, SEM and VSM techniques to study their optical, structural, thermal and magnetic properties. The photocatalytic activity on methylene blue dye using the synthesized nanocatalysts was analyzed and the experimental result was recorded using UV-vis spectrophotometer. The percentage reduction of methylene blue dye was estimated and found to be 99% on irradiation under UV lamp and 2.70% in the absence of UV lamp irradiation. The recyclability of the synthesized catalyst for four successive cycles indicates that the catalyst can be estranged and efficiently reused. The performance of CeTi0.5Fe0.5O3-δ nano photocatalyst was observed to be better than CeTiO3-δ and CeFeO3-δ. The photo-catalytic property of the prepared nanomaterial makes it suitable in amputation of dye effluents from the fabric industries.
