“…Mesoporous zirconia ceramic fibers (MZCF) with a surface area of 293.07 m 2 /g has been reported as a high-affinity phosphate adsorbent having the removal capacity of 222.79 mg/g. The adsorption-desorption study showed that the material was seen to maintain removal capacity of 92.5% after five subsequent cycles (Dong et al 2020). In general, one can conclude that the formation of hydroxyapatite especially for CSH (Leng et al 2019;Zhang et al 2019 (Jiang et al 2013).…”

Nitrogen and phosphorus removal and recovery are considered as one of the interventions to control water bodies' eutrophication by application of various methods. Adsorption is an effective method for phosphate and nitrate removal from wastewater. It is efficient, quick, easy, low-cost and environmentally friendly. Even though different adsorbents have been developed with excellent properties, lack of compilation, lack of consistency in operational conditions, and lack of other important parameters used for direct comparison and practical use selection were observed. The first aim of this review is to provide facts and figures on novel adsorbents used for nitrate, phosphate, and simultaneous nitrate-phosphate removal and recovery. Second, various adsorbents applied for nitrate and phosphate removal have been compared in terms of the number of cycles that the adsorbent used; retained removal capacity (RR); the removal capacity of the adsorbent considering the threshold limit settled by EU and EPA as equilibrium concentration for phosphate (q0.1) and nitrate (q10); and time to reach the equilibrium capacity (t90). Third, based on the afore-mentioned criteria, the best adsorbents is proposed and this is the key novelty of this review work. Moreover, future aspects and challenges regarding nitrate and phosphate removal and recovery are presented.

“…Polyvinyl pyrrolidone (PVP) [85][86][87] is the most popular polymer template because of its excellent solubility. Polyacrylonitrile [20, 88,89], polyethylene oxide (PEO) [90][91][92], and polymethyl methacrylate [93] have also been widely used as polymer matrices. Furthermore, crystallographic inhibitors, such as yttrium hexahydrate nitrate [94][95][96], ethyl orthosilicate [97], and aluminum nitrate [54], are usually added to ensure that the crystal structure of ZrO 2 is unchanged after sintering at high temperatures.…”

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.

In this work, a novel bifunctional zirconium dioxide @ zeolitic imidazolate framework-90 (ZrO 2 @ZIF-90) nanozyme was successfully developed for the catalytic degradation and electrochemical detection of methyl parathion (MP). The ZrO 2 @ZIF-90 nanozyme with phosphatase hydrolysis activity can convert MP into p-nitrophenol (p-NP). The addition of ZrO 2 riched in Lewis acid Zr(IV) sites significantly enhanced the phosphatase hydrolysis activity of ZIF-90. ZrO 2 @ZIF-90 also displayed satisfactory electrocatalytic performance on account of the high surface area, high porosity and powerful enrichment ability of the ZIF-90 and the excellent ion transfer capacity of ZrO 2 . A ZrO 2 @ZIF-90 nanozyme modified glassy carbon electrode (ZrO 2 @ZIF-90/GCE) was then fabricated to analyze p-NP formed through MP degradation. Under the optimized conditions, the developed sensor displayed satisfactory analytical performance with a low limit of detection of 0.53 μmol L -1 and two wide linear ranges (3-10 μmol L -1 and 10-200 μmol L -1 ). ZrO 2 @ZIF-90 nanozyme accomplished to the degradation and electrochemical detection of MP in river water and spiked fruits. This study identifies a promising new strategy for the design of bifunctional nanozymes for the detection of environmental hazards.
