Single-phase BiFeO(3) and BiFeO(3)–Fe(2)O(3) nanocomposite photocatalysts for photodegradation of organic dye pollutants
The application of a novel BiFeO(3) (BFO)–Fe(2)O(3) composite (called BFOF) as a photocatalyst for the degradation of methylene blue is reported. To improve the photocatalytic effectiveness of BiFeO(3), we synthesized the first BFOF photocatalyst by adjusting the molar ratio of Fe(2)O(3) in BiFeO(3)...

description | The application of a novel BiFeO(3) (BFO)–Fe(2)O(3) composite (called BFOF) as a photocatalyst for the degradation of methylene blue is reported. To improve the photocatalytic effectiveness of BiFeO(3), we synthesized the first BFOF photocatalyst by adjusting the molar ratio of Fe(2)O(3) in BiFeO(3) using microwave-assisted co-precipitation. The UV-visible properties of the nanocomposites showed excellent absorption of visible light and reduced electron–hole recombination properties compared to the pure phase BFO. Photocatalytic studies on BFOF10 (90% BFO, 10% Fe(2)O(3)), BFOF20 (80% BFO, 20% Fe(2)O(3)), and BFOF30 (70% BFO, 30% Fe(2)O(3)) have shown that they decompose Methylene Blue (MB) in sunlight better than the pure BFO phase in 70 minutes. The BFOF30 photocatalyst was the most effective at reducing MB when exposed to visible light (94%). Magnetic studies confirm that the most effective catalyst BFOF30 has excellent stability and magnetic recovery properties due to the presence of magnetic phase Fe(2)O(3) in the BFO. |
