| description | Fe-Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub> photocatalytic materials were prepared by modified solution combustion method using bismuth nitrate, citric acid, ammonium chloride and ferric nitrate as raw materials. The influence of Fe<sup>3+</sup> doping on its photocatalytic performance was evaluated by degrading rhodamine B in visible light.XRD,XPS,UV-vis, SEM,HTEM and FT-IR were used to study the effects of different Fe<sup>3+</sup> doping amount on the phase, elemental valence, optical absorption performance, microscopic morphology and particle distribution, crystal surface spacing and chemical structure composition of Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub>.The results show that doped Fe<sup>3+</sup> does not change the phase and morphology of Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub>, but its sheet size is obviously smaller, its thickness is thinner, its optical absorption property is enhanced, and the photoelectron hole recombination ratio is decreased. Compared with pure Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub>, Fe<sup>3+</sup> doping can significantly improve the photocatalytic activity of Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub>.The photocatalytic activity of Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub> is the highest when the doping amount of Fe<sup>3+</sup> is 0.5% (mole fraction), and the decolorization rate of RhB is 75% when exposed to visible light for 50 min, which is 44% higher than that of pure Bi<sub>24</sub>O<sub>31</sub>Cl<sub>10</sub>. |
