Photocatalytic technology holds great promise in renewable energy and environmental protection. Herein, we report the synthesis of a class of polyaniline-sensitized BiOCl core/shell nanosheets with visible-light photocatalytic activity by a one-step oxidative polymerization method and show how the hybrid nanosheet boosts the photocatalytic activity and stability for degradation of Rhodamine B (RhB). In this unique structure, the ultrathin polyaniline (PANI) as a shell with the thickness of about 1-2 nm, can widen the response of the catalyst to visible light to boost photocatalysis and the BiOCl core can promote the separation of photogenerated carriers from the PANI. We demonstrate that the optimized BiOCl/ PANI core/shell photocatalyst shows nearly three times higher photocatalytic activity for the degradation of RhB than pure BiOCl and also shows high stability. This work provides a new strategy for the design of a highly efficient hybrid photocatalyst driven by visible light.

“…The CB photoelectrons of semiconductor B with low reducing ability and the VB holes of semiconductor A with low oxidizing ability recombine. The 4% CdS/BiOCl heterojunction prepared by Lin et al (Lin et al, 2017) showed a 10% higher photoactivity than pristine BiOCl in elimination of RhB, which was due to the direct Z-scheme mechanism (Figure 6C). In a new Z-scheme BiOBr/MnFe 2 O 4 nanocomposite, spontaneous transfer of photoelectron carriers contributed to the photoelectron-hole division and decelerated the electron-hole recombination (Sin et al, 2020).…”

Solar energy transformation over semiconductor-based photocatalysis is an ideal solution to environmental problems and future sustainability. Layered bismuth oxyhalides (BiOX, X = Cl, Br or I) are very attractive and promising photocatalysts in the environment fields. This review summarizes recent advances on the design of BiOX to enhance energy converting efficiency. Especially, the emerging techniques to enhance the photocatalytic behaviors of BiOX are discussed, including non-metal/metal doping, heterojunction engineering, carbon interfacing, coupling with noble metals, defect engineering, and morphology tuning. The application of BiOX composites in wastewater remediation is also reviewed in terms of organic photocatalytic oxidation and heavy metal ion photocatalytic reduction. Finally, the future chances and challenges of BiOX photocatalysts for practical application are summarized. In all, this review well underlies the innovative preparation of BiOX products for environment-related purposes.

“…Thus, it is necessary to modify the photocatalyst to absorb visible light, which accounts for a large proportion of sunlight. A great deal of research has been carried out to promote the photoactivity of BiOCl, including metal and non-metal doping, [19][20][21] morphology control, 22,23 and heterojunction construction. [24][25][26] Among these strategies, heterojunction construction is appropriate as it can concurrently extend the light absorption and improve the charge separation and transfer.…”
