“…Actually, the polarization has been veried to play a key role in the photoinduced charge separation and transmission in ferroelectric photovoltaics, which always lead to the enhanced photoelectric performance. [46][47][48] Even in the organic-inorganic hybrid perovskite solar cells, it is very likely that the polarization could be responsible for their outstanding photovoltaic performances. [49][50][51] Thus, aer poling the HDA-BiI 5 lm at different electric elds, the effect of ferroelectric polarization on the photoelectric properties of the (HDA-BiI 5 )-based solar device has been detected under sunlight simulator illumination (Fig.…”

“…Moreover, Bi2WO6 is recognized as one of the few n-type semiconductors resistant to photocorrosion in aqueous solutions. Therefore, Bi2WO6 has been synthesized in a variety of morphologies, such as microspheres [11,14], nanofibers [15,16], nanosheets [17][18][19],…”

In this work, a serious of Pr 3+ doped Bi2WO6 had been prepared by one-step hydrothermal method without using any additive. XRD results showed that the Pr 3+ doped Bi2WO6 possessed pure orthorhombic phase. XRD patterns shifted to higher angles with the doping amount of Pr 3+ increasing indicated that Pr 3+ was doped into the lattice of Bi2WO6. UV-vis DRS results revealed that the band gap was narrowed by Pr 3+ doping. SEM and TEM images showed that the Pr 3+ doped Bi2WO6 presented 3D flower-like microspheres constructed by many nanosheets. The photocatalytic activities of the as-prepared samples were evaluated by using rhodamine B (RhB) as the target organic pollutant. It was found that 1% Pr-Bi2WO6 exhibited excellent photocatalytic performance, as well as good stability and reusability. The improved photocatalytic activity can be ascribed to the optimum optical absorption activity, the larger specific surface area and the morphology of microspheres which resulted in the effective separation of the photogenerated electron hole pairs. In addition, the photocatalytic mechanism had been discussed according to the radical-trapping experiments.
