“…PO 4 3− , which possesses a large negative charge, is postulated to help the electron-hole pairs separation, which plays an important role in its excellent photocatalytic activity. Duo et al fabricated BiPO 4 /BiOBr via a facile one-step hydrothermal method and BiPO 4 /BiOBr composite displayed higher photocatalytic activity than pure BiPO 4 and BiOBr for the degradation of Rhodamine B under visible light irradiation [41]. Dong et al reported that BiOBr/rod-like BiPO 4 were synthesized by a two-step method and it performed optimal photocatalytic activity of degrading Rhodamine B under visible light [42].…”

“…The visible light absorption intensity is enhanced with coupling MIL-88B(Fe) in BiOBr/MIL-88B(Fe) composites, which indicates that the binary hybrid structure can produce more electron hole pairs under the same visible light irradiation and result in a more efficient utilization of the sunlight. Therefore, it can be inferred that the introduction of MIL-88B(Fe) is beneficial to improve the light absorption of BiOBr (Duo et al, 2015). This inference can be verified by the photocatalytic degradation of RhB under visible light irradiation.…”

“…However, the photocatalytic activity of BiOBr/MIL-88B(Fe) significantly decreases and only 20.7% of RhB was degraded when sodium formate was added. This indicates that h þ is the main active species in the photocatalytic process under visible light irradiation (Duo et al, 2015). Photoelectrochemical measurements are often used to gain an insight into the excitation and transfer of photogenerated charge carriers in photocatalysts Zhang et al, 2012;Zhang et al, 2013).…”

In this study, a novel composite containing an iron based metal-organic framework (MOF) and BiOBr was successfully synthesized by a simple method, and was fully characterized by X-ray diffraction patterns, Fourier transform infrared spectra, UV-vis diffuse reflectance spectra, and transmission electron microscopy. Moreover, the photocatalytic activities of BiOBr/MIL-88B(Fe) composites and the pure materials were evaluated by measuring the degradation of Rhodamine B under visible light. The results show that the composite exhibits better photocatalytic activities than pure materials, which can be ascribed to the high adsorption capacity of MIL-88B(Fe) and the enhanced separation of photogenerated charge carriers from assembly of MIL-88B(Fe) on BiOBr. And the effects of various operating parameters such as catalyst dosage, medium pH, the mass ratio of BiOBr, and MIL-88B(Fe) and the dye initial concentration on the degradation of RhB have been studied.

“…It was found that the local heterojunction between the photocatalysts pair facilitates the separation of the photogenerated e − /h + pairs (mechanism C, see Figure 2c). A photocatalysts with enhanced electron-hole separation and excellent photocatalytic performance was investigated by Duo et al [215,217]. The methyl orange solution and Rhodamine B were used as a model substance in degradation under simulated sunlight.…”

Among all kinds of green earth and renewable energy projects underway, semiconductor photocatalysis has received wide interest because it provides an easy way to directly utilize the energy of either natural sunlight or artificial indoor illumination. TiO 2 , the most widely used photocatalyst, due to its wide band gap, can only be activated under UV irradiation, and thus, the development of novel semiconductor photocatalysts makes a significant advancement in photocatalytic functional materials. One of the effective strategies to overcome this shortcoming is photosensitizing these wide band gap semiconductors with narrow band gap semiconductors which have proper energy levels. This method can not only improve the photocatalytic activity, due to increasing visiblelight-harvesting efficiency, but also can decrease the recombination of the charge carriers, because the formation of n-n or n-p heterojunctions between the combined semiconductors can induce internal electric fields between them. In this regard, this review presents some unitary, binary, and ternary non-TiO 2 photocatalysts used for the degradation for organic pollutants and for water splitting.
