Metal‐Organic Frameworks and Electrospinning: A Happy Marriage for Wastewater Treatment

“…[274] The SiO 2 /MIL-100(Fe) nanofiber composites have the following advantages over other reported MOF-based nanofibers: i) the electrospun inorganic SiO 2 fiber possesses high preparation yield, good flexibility, and high thermal stability, ii) decoration of MIL-100(Fe) particles on the surface of electrospun SiO 2 fibers addressed the agglomeration and difficult recycling of the MIL-100(Fe) powders, and iii) the MIL-100(Fe) particles can be directly grown on the surface of electrospun SiO 2 fibers via a simple LbL assembly strategy at low temperatures with no requirement for complicated synthetic procedures and hazardous acids. [275,276] Moreover, the electrospun SiO 2 /MIL-100(Fe) fiber composite exhibited good photocatalytic performance and reusability for RB dye photodegradation under visible light irradiation. Accordingly, the photocatalytic activity of the electrospun SiO 2 /MIL-100(Fe) fiber composite remained above 80% within 90 min illumination after three consecutive cycles.…”

Electrospun Semiconductor‐Based Nano‐Heterostructures for Photocatalytic Energy Conversion and Environmental Remediation: Opportunities and Challenges

“…[376,377] To further extend the light absorption region, the TiO 2 component in the above SiO 2 nanofiber-based flexible selfsupporting photocatalysts has been replaced by the visible light-driven nanostructures, such as Bi 2 WO 6 nanoplatelets, CuO NPs, Bi 2 WO 6 NPs, and MIL-100(Fe), and g-C 3 N 4 . [378][379][380][381][382] These flexible nanofiber photocatalysts have high visible light photocatalytic activities, good tailorability, and excellent reusability for the application of photocatalytic organic pollutant decomposition. In addition, the flexible inorganic nanofibrous membranes have been also reported through the electrospinning preparation of the ion-doped TiO 2 , SiO 2 /TiO 2 , and carbon-based nanofiber systems under the suitable preparation conditions.…”

Enhanced visible‐light‐driven photocatalytic application for water purification and hydrogen evolution by large‐sized nanofilm‐constructed hierarchical porous g‐C3N4/SiO2

“…The frequency band at 1648 cm −1 is designated as typical C = N tensile vibration. The bands occur at 1243, 1319, and 1430 cm −1 respectively, attributing to C-N stretching [30]. The signal peak of the triazine ring appeared at 808 cm −1 , indicating that the typical structure of g-C 3 N 4 was successfully generated.Figure2Cshows the N 2 adsorption-desorption isotherm of g-C 3 N 4 /LNCHPS.…”
