Studies of electrospinning process of zirconia nanofibers

Submicron fibers as a morphological improvement of amorphous zirconium oxide particles and their utilization in antimonate (Sb(v)) removal

“…10 In addition to different crystal structures, zirconium oxide can be prepared in different morphologies, such as nanopowders, microspheres, grains, lms and bers. 7,[11][12][13][14][15] One method to produce nanocrystalline zirconium oxide is a precipitation method in which zirconium precursor, which is rst dissolved into acid, is precipitated with base causing the formation of small colloids that can stay monodispersed or form aggregates during a drying process. 16 Precipitated materials usually have a large specic surface area and porosity but the use of such small particles is rather challenging in some applications, for example, in xed-bed columns.…”

The influence of zirconia precursor/binding polymer mass ratio in the intermediate electrospun composite fibers on the phase transformation of final zirconia nanofibers

“…For comparison, ZrOCl 2 /PVP composite fibers calcined at 800 8C had the average diameter 80 nm (0.4:1) [15] and 850 nm (5.5:1) [22]. The average diameter of the ZrOCl 2 / PVA (0.5:1) composite fibers calcined at the same temperature was around 120 nm [23].…”

Electrospun Nanofibers for Air Filtration

“…Electrospun ceramic nanofibrous membranes which combine the unique thermal stability and nanometer fiber diameter can be used as the high-temperature filtration media in the range of 1,000 ı C without expensive pretreatments for hot waste gases. Over the past decade, considerable effort has been devoted to fabricating ceramic nanofibers, including SiO 2 [73], Al 2 O 3 [74], ZrO 2 [75], and so on; however, the brittleness of current ceramic membranes significantly limits their practical applications. Recently, silica nanofibrous (SNF) membranes with remarkable flexibility and thermal stability were prepared by a facile combination of electrospinning and solgel methods [76][77][78][79].…”
