“…Such synthesized materials retain the microstructure of the biotemplates and possess arbitrarily added properties. Generally, biotemplates are categorized into two types, i.e., plant origins (e.g., ceiba, cogon, and jute) [33,57,58] and animal origins (e.g., silk and sponge) [59]. Each biotemplate has a unique structure and can be selected according to the application requirements.…”

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.

“…Zirconia (ZrO 2 ) fiber is commonly used as an industrial heat insulator, because of its excellent heat‐insulating properties. It has been used as a lining for various high‐temperature furnaces, as a heat‐insulating layer in crystal growing furnaces, as insulating material in atomic energy reactors, etc . Zirconia ceramic fibers and their derivative products (fiber cloth, fiber blankets, fiberboard, and fiber paper) are considered to be the highest grade thermal insulation materials.…”

Zirconia (ZrO 2 ) fibers are lightweight polycrystalline refractory materials that have long service life, and are suitable for use at ultra-high temperatures (above 1600°C). In this study, biomorphic ZrO 2 ceramic fibers were prepared by a simple impregnation method using a zirconic solution using cotton fibers as a biomaterial template. First, cotton fibers were immersed in a zirconyl chloride octahydrate (ZrOCl 2 Á8H 2 O) solution, which also contained yttrium nitrate hexahy-The precursor fibers were sintered at different temperatures to produce the final biomorphic ZrO 2 ceramic fibers in air. Phase analysis, microstructures, thermoanalysis, and thermal conductivity were investigated. The experimental results show that these ZrO 2 ceramic fibers faithfully retain the morphologies of the cotton fibers: parts of the fibers are hollow, allowing greater heat insulation than traditional ZrO 2 fibers. In this study, we utilized the morph-genetic theory to prepare insulation material, providing a new and effective way to fabricate materials with excellent heat-insulating properties.

“…There are various synthetic fibers [9,10] and natural polymers [11,12] which have been used in template method of obtaining inorganic fibers. The most commonly used natural polymer is cellulose [4][5][6][7][8] which is cheaper and more available material than synthetic polymers, besides that cellulose is the most common plant polymer.…”

The main focus of this study is to investigate the influence of functional groups of cellulose and its derivatives on properties and morphology of alumina materials obtained by template synthesis. Cyanoethyl-, amidoethyl-and carboxymethylcellulose were synthesized from bleached softwood pulp and they were used as templates for alumina materials preparation. By means of methods of scanning electron microscopy and nitrogen physical sorption it was shown that properties and type of functional groups of template can influence on the morphology and textural characteristics of obtained ceramic materials. The alumina specimens that obtained from cyanoethyl-, amidoethylcellulose have thicker fibers and two times increased surface area in comparison with alumina obtained from initial cellulose but the one formed by carboxymethylcellulose have thin alumina fibers and three times decreased surface area. Thus, by regulating properties and type of template it is possible to obtain ceramic materials with desired properties and morphology.
