Photocatalysis under visible light and NIR light irradiation.
(a) Amounts of the decomposed RhB under a 20 W fluorescent lamp light (400–760 nm) when using different photocatalysts; (b) A possible role of ferroelectricity and magnetism for the photocatalysis process; (c) Amounts of the decomposed RhB by BFTO and BFCTO-0.25 under a condition that a 400/580/760 nm long-wave-pass filter was placed next to a halogen reflector lamp (400 ~ 900 nm); inset is the integrated light absorption of BFCTO-0.25 in different wavelength ranges; (d) the full visible light photocatalytic degradation of BFCTO-0.25 (50 mg)/RhB (5 mg/L, 50 mL) of 3 hours at 343 K.
