Finding effective strategies to design efficient photocatalysts and decompose refractory organic compounds in wastewater is a challenging problem. Herein, by coupling element doping and constructing heterostructures, S‐scheme CdS QDs/La‐Bi2WO6 (CS/LBWO) photocatalysts are designed and synthesized by a simple hydrothermal method. As a result, the RhB degradation efficiency of the optimized 5% CS/LBWO reached 99% within 70 min of illumination with excellent stability and recyclability. CS/LBWO shows improvement in the adsorption range of visible light and promotes electron–hole pair generation/migration/separation, attributing the superior degradation performance. The degradation RhB mechanism is proposed by a free radical capture experiment, electron paramagnetic resonance, and high‐performance liquid chromatography‐mass spectrometry results, indicating that h+ and •O2– play a significant role during four degradation processes: de‐ethylation, chromophore cleavage, ring opening, and mineralization. Based on in situ irradiated X‐ray photoelectron spectroscopy, Mulliken electronegativity theory, and the work function results, the S‐scheme heterojunction of CS/LBWO promotes the transfer of photogenerated electron–hole pairs and promotes the generation of reactive radicals. This work not only reports that 5% CS/LBWO is a promising photocatalyst for degradation experiments but also provides an approach to design advanced photocatalysts by coupling element doping and constructing heterostructures.

“…Previous studies have demonstrated that the incorporation of doped TiO 2 , [42] ZnO, [43] and Ag [44] nanoparticles into SF mats can improve their antibacterial activity and photocatalytic properties. Wang et al [45] synthesized Bi 2 MoO 6 /Ag 3 PO 4 @SF (BMO/ APO@SF) mats by electrospinning technique (Figure 2a-c). BMO/APO imparts excellent photocatalytic activity to the composite mats, achieving 100 % degradation of ciprofloxacin within 80 min, five times that of pure SF mats.…”

The improper and inadequate treatment of industrial, agricultural, and household wastewater exerts substantial pressure on the existing ecosystem and poses a serious threat to the health of both humans and animals. To address these issues, different types of materials have been employed to eradicate detrimental pollutants from wastewater and facilitate the reuse of water resources. Nevertheless, owing to the challenges associated with the degradation of these traditional materials post‐use and their incompatibility with the environment, natural biopolymers have garnered considerable interest. Silk protein, as a biomacromolecule, exhibits advantageous characteristics including environmental friendliness, low carbon emissions, biodegradability, sustainability, and biocompatibility. Considering recent research findings, this comprehensive review outlines the structure and properties of silk proteins and offers a detailed overview of the manufacturing techniques employed in the production of silk‐based materials (SBMs) spanning different forms. Furthermore, it conducts an in‐depth analysis of the state‐of‐the‐art SBMs for water treatment purposes, encompassing adsorption, catalysis, water disinfection, desalination, and biosensing. The review highlights the potential of SBMs in addressing the challenges of wastewater treatment and provides valuable insights into prospective avenues for further research.

“…According to this literature survey, electrospun nanofibers possess at least five advantages, including the following. (1) In contrast to the powder-type photocatalysts in the slurry system, which can be agglomerated during successive utilization, anchoring the photocatalyst on an electrospun mat leads to its stability improvement. , (2) A simple separation of free-standing photocatalyst film as a floating water treatment system facilitates its practical applications. , (3) The large surface area of the electrospun nanofibers promotes the adsorption of the organic pollutants and enhances the photodegradation efficiency. , (4) Functionalization of different chemical groups on polymeric electrospun nanofibers can boost the adsorption ability for water treatment. , (5) One-dimensional photocatalyst nanofibers can facilitate quick charge transfer due to their long axial ratio and enhance electron–hole separation for efficient photocatalytic activity . All of these advantages along with the simple, affordable, and large-scale production ability make the electrospinning method a promising technique for various photocatalytic applications. , …”

Electrospinning is a simple and cheap process for forming one-dimensional (1D) nanofibers with controllable size, morphology, and chemistry. Besides these, the ultrahigh surface area with industrialization capability has attracted extensive interest in the research community. On the other hand, a photocatalytic process is a promising method for degrading organic pollutants that cannot be removed by conventional wastewater treatment. This review focuses on the recent progress of electrospun nanofibers for the photocatalytic degradation of water pollutants. The linkage between the electrospinning technique and the photocatalytic process is classified into two main categories: (1) polymeric electrospun nanofibers as a sacrificed template to form 1D photocatalysts and (2) polymeric electrospun nanofibers as a carrier of photocatalyst materials. We have thoroughly discussed the principles and fundamental issues of electrospinning as well as two main strategies to design and fabricate nanofiberbased photocatalysts for the ideal photodegradation of organics pollutants. The results of data mapping using VOSviewer demonstrated the recent trend and the importance of this field among researchers and engineers. Moreover, we have elaborated on the limitations and potential benefits of the two categories of electrospinning-based photocatalyst fabrication and practical application that will open new directions for future research.
