Discharging dye contaminants into water is a major concern around the world. Among a variety of methods to treat dye-contaminated water, photocatalytic degradation has gained attention as a tool for treating the colored water. Herein, we review the recent advancements in photocatalysis for dye degradation in industrial effluents by categorizing photocatalyst materials into three generations. First generation photocatalysts are composed of single-component materials (e.g., TiO 2 , ZnO, and CdS), while second generation photocatalysts are composed of multiple components in a suspension (e.g., WO 3 /NiWO 4 , BiOI/ZnTiO 3 , and C 3 N 4 /Ag 3 VO 4 ). Photocatalysts immobilized on solid substrates are regarded as third generation materials (e.g., FTO/WO 3 -ZnO, Steel/TiO 2 -WO 3 , and Glass/P-TiO 2 ). Photocatalytic degradation mechanisms, factors affecting the dye degradation, and the lesser-debated uncertainties related to the photocatalysis are also discussed to offer better insights into environmental applications. Furthermore, quantum yields of different photocatalysts are calculated, and a performance evaluation method is proposed to compare photocatalyst systems for dye degradation. Finally, we discuss the present limitations of photocatalytic dye degradation for field applications and the future of the technology.

Preparation of superhydrophobic surfaces capable of recovering both the surface chemistry and hierarchical structure is still a challenge. In this work, all-damage-healable superhydrophobic surface was fabricated by assembly of superhydrophobic and hierarchical BiOCl on lignocellulosic substrates. Fibers having thermally responsive behavior, the main component of lignocellulosic materials, act as the underlying movable substrates. By a simple heating treatment, fibers can convey the undamaged neighbored superhydrophobic coating to the damaged area. In 2 this way, the loss of superhydrophobicity caused by rigorous mechanical destructions, even deep cuts of one hundred of micrometers wide, can be restored, mimicking the self-healing mechanism of human skin. Superior self-healing ability in surface chemistry was also confirmed. Meanwhile, the as-prepared superhydrophobic surfaces demonstrated reliable photocatalytic ability, a useful property for resisting organic contaminations. Interestingly, it was found that the photocatalytic activity can be enhanced by tuning the surface wettability. This work reported the first use of substrate material's inherently thermally responsive property to demonstrate self-healing superhydrophobic surface with photoctalyticity, which not only promotes the application of superhydrophobic materials in complex environment, but also opens up a new perspective in designing durable superhydrophobic materials.

The construction and regulation of heterogeneous interfaces are beneficial to improve solar light harvesting and photocharge separation of hybrid BiOCl-based photocatalysts, which are attributed to the synergistic effects that originate from the integrated interaction between disparate components. With the rapid development of synthetic technologies, hybrid BiOCl-based micro-/nanostructures with diversified components, morphologies, and sizes have been well prepared. Moreover, hybrid BiOCl-based photocatalysts have presented a promising potential for various photocatalytic applications, such as organic pollutant degradation, hydrogen production, NO removal, CO2 reduction, heavy metal ion detection, disinfection, nitrogen fixation, and alcohol oxidation. Previously, several review articles have mainly summarized the advances made in synthetic methods, morphological control, modification strategies, and applications of the bare BiOCl micro-/nanostructures. However, a comprehensive overview based on the type of species and the corresponding correlations between microstructures, performances, as well as photocatalytic mechanisms has been less reported for hybrid BiOCl-based photocatalysts so far. Therefore, a comprehensive understanding of the basic theory and research progress of hybrid BiOCl-based photocatalysts is imperative. This review aims to provide an overview of the important advances made in eight types of hybrid BiOCl-based photocatalysts, including metal/BiOCl, metal oxide/BiOCl, metal sulfide/BiOCl, BiOX (X = Cl, Br, I)/BiOCl, AgX (X = Cl, Br, I)/BiOCl, organics/BiOCl, carbon/BiOCl, and other BiOCl-based multicomponents. In each classification, the synthetic methods, modification strategies, relationships between interfacial microstructures, and enhanced performances are discussed based on some typical examples. Additionally, some scientific issues and potential directions are also given. Hopefully, this review paper will provide a useful reference for researchers currently focusing on exploring new BiOCl-based photocatalysts.
