Recent Developments of Electrospinning-Based Photocatalysts in Degradation of Organic Pollutants: Principles and Strategies

“…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. , …”

Hierarchically Structured NH2‐MIL‐125/TiO2/Cellulose Composite Membranes With Enhanced Photocatalytic Performance

“…However, there are serious limitations for pure MOFs as being applied as photocatalytic materials, such as low separation and transfer efficiencies, fast recombination of charge carriers, and so on. Therefore, a number of MOFs‐based hybrid photocatalysts have emerged [11,12] . For examples, the UiO‐66/g‐C 3 N 4 hybrid with the UiO‐66 octahedrons coated on the surface of the g‐C 3 N 4 nanosheets was synthesized by a facile annealing method, which was employed for the photocatalytic degradation of the methylene blue (MB) solution under visible light irradiation [13] .…”

Photo-Fenton Antifouling Membrane Based on Hydrophilized MIL-88A for Sustainable Treatment of Colored Emulsions

“…Colored emulsions challenge traditional oil–water separation techniques, since special wettability alone cannot effectively remove dyes. Adsorption and photocatalysis are often used to remove dyes from solution. − Several researchers have proposed methods to filter aqueous solutions of adsorbed dyes. − Cevik’s team synthesized a nitrogen-doped multilayer molybdenum carbide and molybdenum oxide nanosheet that performs gravity-driven dye removal without applying pressure . Xie and co-workers proposed a carbamide-modified graphene oxide membrane with 99% removal of Congo red, peacock green, and crystal violet .…”
