Electrospun nanofibrous hybrid materials have several advantageous characteristics, including easy preparation, high porosity, and a large specific surface area. Meanwhile, they can be more suitable for colorimetric detection in environmental and food areas than organic materials due to the advantages of inorganic nanomaterials, i.e., stability, low toxicity, and durability. In addition to being able to immobilize nanomaterials to avoid particle aggregation, electrospinning hybrid materials also have the advantages of high specific surface area and high porosity, which is beneficial for constructing colorimetric sensors. This review mainly summarizes the fabrication methods of electrospun nanofibrous hybrid materials and the application of electrospun nanofibrous hybrid material based colorimetric sensors. First, the preparation strategies of electrospun nanofibrous hybrid materials were discussed. Then, the applications of the obtained electrospun nanofibrous hybrid materials in the colorimetric sensors for environmental molecules in the gas and liquid phase were further investigated. Finally, this review looks forward to the development prospects and challenges of electrospun hybrid materials in practical applications of colorimetric sensors in order to support the application of colorimetric sensors in practical detection.

“…Phosphorus is an important nutrient resource for plant growth; however, it causes eutrophication in water bodies. 90 The recovery of PO 4 3− from wastewater is of great concern for controlling eutrophication and in the sustainable use of phosphorus. PNC adsorbents are promising materials for the efficient recovery of PO 4 3− from wastewater which can be used as a fertilizer in soil amendments.…”

“…19 The substantial number of mesopores in nanofiber sphere-supported TiO 2 promotes adsorption of aniline in the "dark reaction" prior to photodegradation, while the abundance of amidoxime groups can increase the adsorption sites of Sb(V), thereby increasing the rate of Sb(V) reduction. 20 A Zn(OH) 2 /DETA-amidated PAN fiber for the removal and recovery of phosphate from wastewater exhibited a maximum adsorption of about 108.0 mg g −1 at 20 min 21 Due to the synergistic adsorption between the amine groups and γ-AlOOH crystals, the layered aminated PAN/γ-AlOOH electrospinning composite nanofibers exhibited high adsorption capacities toward Pb(II), Cu(II), and Cd(II). 22 Therefore, the introduction of functional groups into electrospinning nanofiber materials holds promising prospects for wastewater treatment.…”

The significant threat posed by the high toxicity of heavy metals and antibiotics in water pollutants has prompted a growing emphasis on the development of highly efficient removal methods for these pollutants. In this paper, flexible electrospinning polyacrylonitrile (PAN) nanofiber-supported CdBi 2 S 4 was synthesized via a hydrothermal method, followed by amination treatment with diethylenetriamine (DETA). The as-prepared CdBi 2 S 4 /NH 2 − PAN nanofiber, enriched with sulfur vacancies, demonstrated outstanding visible-light trapping ability and a suitable band gap, leading to efficient separation and transport of photogenerated carriers, ultimately resulting in exceptional photocatalytic capability. The optimal 3-CdBi 2 S 4 /NH 2 −PAN nanofiber achieved impressive reduction rates of 92.26% for Cr(VI) and 96.45% for tetracycline hydrochloride (TCH) within 120 min, which were much higher than those for CdS/NH 2 −PAN, Bi 2 S 3 /NH 2 −PAN, and CdBi 2 S 4 /PAN nanofibers. After five cycles, the removal rate of the CdBi 2 S 4 /NH 2 −PAN nanofiber consistently remained above 90%. Their ease of separation and recovery from the application environment contributes to their practicality. Additionally, compared with conventional suspended particle catalyzers, the composite nanofiber exhibited remarkable flexibility and self-supporting properties.
