Enhanced degradation of organic pollutants using Bi 25 FeO 40 microcrystals as an efficient reusable heterogeneous photo-Fenton like catalyst

“…The Eg value of Bi 25 FeO 40 based on the plots of (ahv) 2 versus photon energy (hv) (Fig. 4b) [20][21][22][23][24] have a lower energy gap, the photoabsorption of Bi 25 FeO 40 moves to high wavelength. Wei et al [25] reported that the band gap of BiFeO 3 is about 2.55 eV (486 nm) by the linear extrapolation and the band gap of Bi 25 FeO 40 is much lower than BiFeO 3 .…”

Selective synthesis on structures and morphologies of BixFeyOz nanomaterials with disparate magnetism through time control

“…Sillenite-phase bismuth oxides are considered as wide-band semiconductors owning both high photo-sensibility and carrier mobility [23][24][25]. It is reported [26] that sillenite-structure Bi 25 FeO 40 exhibits strong absorbance in the region of both UV and visible light, and is a promising visible-light photo-catalyst.…”

Simple Low Temperature Technique to Synthesize Sillenite Bismuth Ferrite with Promising Photocatalytic Performance

“…These band gap values are very close to those of early investigations on sillenite-type bismuth ferrites. 26 , 27 Moreover, compared to some other sillenite materials such as Bi 25 GaO 39 , Bi 12 GeO 20 , Bi 12 SiO 20 , and Bi 24 AlO 39 , 17 , 42 − 44 the as-synthesized S-BFO samples have a lower energy gap which will give large spectral coverage, implying their potential application in wastewater treatment as promising UV and visible light active photocatalysts. The steady-state PL spectra of all the samples were recorded at room temperature to qualitatively understand the electron–hole pair recombination rate.…”
