Geo et al. [22], for example, confirmed that BFO nanoparticles, in addition to UV radiation, have excellent potential for MO degradation when exposed to visible light (**Figure 4 (a)**). As shown in **Figure 4 (b)**, Geo et al. found that Gd-doped BFO nanoparticles can enhance their photocatalytic properties by increasing the rate of RhB degradation from 79 percent in BFO to 94 percent in Bi0.9Gd0.1FeO3 [26]. As a result, there is strong pressure to develop alternatives. Due to the p-n junction built into the p-type BFO interface and the n-TiO2 type, the presence of BFO nanoparticles improves the image degradation performance under visible light while preventing the reunification of electron-generated electrons. As shown in **Figure 4 (a)**, the efficiency of the depletion of TiO2 nanofibers in MB is only 3% after 150 minutes, but this performance can be achieved to nearly 100% when 5 mol% and 10 mol% BiFeO3 nanoparticles are incorporated in TiO2 nanofibers [64]. Moreover, boosting the density of BFO nanoparticles has a negative impact on photocatalytic activity because they can obscure active sites of TiO2 and inhibit electron transfer to the BFO / TiO optical connector. Correspondingly, under visible light, the performance of BFO / TiO2 nanotubes image conversion can be increased from 0.7 percent for pure TiO2 nanotubes to 3.2 percent for BFO/TiO2 composite nanotubes [50], which can be seen in **Figure 4 (b)**. Other abnormalities which have been encountered to improve photocatalytic function include BFO-graphene and nanohybrid [52]. The improved magnetic performance and optical illumination of the BFO nanoparticles described above make them excellent candidates for advanced development and application.
