Recent advances in ZrO2 nanofibers: From structural design to emerging applications

Abstract

One-dimensional (1D) zirconium dioxide nanofibers (ZrO 2 NFs), as an important inorganic material, have attracted significant attention because of their unique structural characteristics, outstanding chemical/thermal stability, and excellent optical/electronic properties. The biotemplate method, phase inversion method, centrifugal spinning, and electrospinning are facile and highly versatile approaches for the synthesis of ZrO 2 NFs, which have great potential in many emerging applications, such as thermal insulation, air filtration, water purification, catalyst supports, dye-sensitized solar batteries, and lithium-ion batteries. In this review, strategies for synthesizing ZrO 2 NFs with various structures, such as porous, hollow, layered, and even 3D selfassembled structures, are described and analyzed in detail. Recent revolutionary progress in mitigating the brittle nature of ceramics and constructing flexible ZrO 2 NFs, as well as their deformation mechanisms, is also discussed. Then, achievements concerning the application fields of ZrO 2 NFs in thermal insulation, environmental remediation, catalysis, and batteries are presented. Finally, we provide a comprehensive summary of the critical challenges and future perspectives on ZrO 2 NFs. This review is envisioned to guide future research on novel ZrO 2 NFs for emerging applications.

Advancements in Thermal Insulation through Ceramic Micro-Nanofiber Materials

“…These stabilizers include yttrium oxide, calcium oxide, and magnesium oxide. Their incorporation during the fabrication process of ZrO 2 helps prevent the occurrence of this undesired phase transition and subsequent structural integrity degradation [72].…”

Carbon/ZrO2 aerogel composite microtube superfoam

“…[11][12][13] As a kind of inorganic material, Zirconium dioxide (ZrO 2 ) ber is a widely used high-temperature insulation material due to its the lowest thermal conductivity (among all metal oxides), ultrahigh temperature resistance and long service lifetime. 14,15 However, the thermal insulation properties of zirconia solid ber have almost no room for further improvement due to their microstructural limitations. 16,17 Therefore, it is necessary to nd new microstructures to further improve the thermal insulation properties of ZrO 2 materials.…”

Signal-Enhanced Immunosensor-Based MOF-Derived ZrO2 Nanomaterials as Electrochemiluminescence Emitter for D-Dimer Detection

“…For instance, traditional luminol and [Ru­(bpy) 3 ] 2+ luminescent materials have been extensively investigated, along with novel semiconductor nanomaterials like perovskite QDs and graphene QDs. – Metal oxide nanomaterials, including TiO 2 and ZnO QDs, have also attracted considerable attention due to their strong ECL activity. , However, most research on metal oxide nanomaterials has primarily focused on their cathodic ECL performance, with limited studies on their anodic ECL performance. ZrO 2 nanomaterials possess excellent chemical stability, optical activity, and biocompatibility, making them widely applicable in areas such as ceramic products, catalysis, and biomedical engineering. – In this study, ZrO 2 nanomaterials were synthesized through calcination of the MOF material UiO-67. The synthesis method is straightforward and has higher reproducibility.…”
