“…The resultant nanofibrous membranes possessed good catalytic performance for methylene blue, which could be degraded by 96% in 20 min, and the removal rate could reach 0.148 min −1 . In addition, there were also some reports about the removal of phosphate and mercaptan from water, demonstrating the advantages of the application of electrospun SNFs for the adsorption of various pollutants [ 200 , 201 ].…”

One-dimensional (1D) SiO2 nanofibers (SNFs), one of the most popular inorganic nanomaterials, have aroused widespread attention because of their excellent chemical stability, as well as unique optical and thermal characteristics. Electrospinning is a straightforward and versatile method to prepare 1D SNFs with programmable structures, manageable dimensions, and modifiable properties, which hold great potential in many cutting-edge applications including aerospace, nanodevice, and energy. In this review, substantial advances in the structural design, controllable synthesis, and multifunctional applications of electrospun SNFs are highlighted. We begin with a brief introduction to the fundamental principles, available raw materials, and typical apparatus of electrospun SNFs. We then discuss the strategies for preparing SNFs with diverse structures in detail, especially stressing the newly emerging three-dimensional SiO2 nanofibrous aerogels. We continue with focus on major breakthroughs about brittleness-to-flexibility transition of SNFs and the means to achieve their mechanical reinforcement. In addition, we showcase recent applications enabled by electrospun SNFs, with particular emphasis on physical protection, health care and water treatment. In the end, we summarize this review and provide some perspectives on the future development direction of electrospun SNFs.

“…A systematic design of desired chemical protective materials requires optimization of two characteristics: hierarchical porous architectures with large inner cavities, as a peculiar adsorptive capacity toward vesicant agents, and robust mechanical properties, which impact the durability and reusability in substantial long-term performance. Over the last decade, porous materials, such as zeolites, metal–organic frameworks, and porous organic polymers, have emerged as promising candidates for the adsorption of CWAs. − Despite their conspicuous potential, the vital problem with porous materials is their natural powder form, which is not the desired configuration for protective clothing. , In contrast, adsorbents deposited on or incorporated into fibrous membranes can considerably facilitate handling and implementation. , However, particle aggregation may induce decreased available adsorbent sites and consequently reduced activity.

Poisons and poisonous weapons in armed conflict, especially chemical warfare agents (CWAs), pose serious threats to global security. Porous materials have recently been regarded as promising candidates to defend personnel in a CWA-contaminated environment, but challenges remain for integrating these materials into protective garments without sacrificing the intrinsic flexibility of fibers. Here, we report a rigid−flexible coupling hypercross-linking methodology to create flexible sponge-like nanofibers featuring hierarchical radial gradient porous nanoarchitectures, in which the inner structure is a mesoporous multichambered network, and the outer structure is a dense domain with a microporous network structure. Experimental and computational evidence supports the contention that sponge nanofibers with distinctive pore topology and robust bendability can be designed by manipulating the flexibility of building blocks. The resulting heterogeneous nanofibers exhibit integrated properties of spatially selective superstructures, abundant micropores, interconnected mesopores, a high surface area (579 m 2 g −1 ), remarkable flexibility, and exceptional CWA affinity, which are extraordinarily effective for adsorptive performance (498 mg g −1 ). The successful synthesis of these materials might inspire the development of chemical protective materials in an efficient, self-standing, and structurally adaptive form.
