Preparation and characterization of tetragonal-ZrO2 nanopowders by a molten hydroxides method

Microwave assisted sol–gel synthesis of tetragonal zirconia nanoparticles

“…Some of the methodologies such as oxidation of ZrCl 2 by molecular oxygen [12], molten hydroxides method [13] non-hydrolytic sol-gel reaction between isopropoxide and ZrCl 4 [14], sol-gel template technique [15,16] are developed to prepare nanocrystalline ZrO 2 . Microwave assisted synthesis of nanocrystalline materials has attracted much attention in recent years because of its several advantages such as unique synthetic pathways, rapid heating rates, short processing durations, uniformity and low power requirements [16][17][18][19][20][21][22][23][24].…”

Facile corrosion synthesis and sintering of disperse pure tetragonal zirconia nanoparticles

“…Wang et al explored a molten hydroxides method to prepare pure t-ZrO 2 nanoparticles using inorganic zirconium salts as zirconium source. The obtained t-ZrO 2 particles are aggregates of fine primary particles [29]. Our t-ZrO 2 nanoparticles calcined at 400°C for 2 h and 500°C for 0.5 h and HCl-corroded in an autoclave at 120°C for 75 h not only have fine average sizes of 4.5 and 6 nm and narrow size distributions of 2-11 and 3-12 nm, respectively but also are pure, fully disperse, and of high crystallinity.…”

A Zirconium Oxide Nanoparticle Modified Screen‐printed Electrode for Anodic Stripping Determination of Daclatasvir Dihydrochloride

“…From which, the two pyrrolidine groups have been oxidized, indicating the formation of a DAC‐ZrO 2 complex through chelation of amino groups in DSV.2HCl with pair of electrons on oxygen atoms of ZrO 2 nanoparticles. This complex with cubic structure of ZrO 2 leads to an increase in the electrode surface area, increasing its sensitivity . From the plot relation of Ip vs. pH (Figure ), it is clear that the peak intensity increased to a high value at pH 5.0 for ZrO 2 ‐MSPE and after that, the peak intensity decreases because the best result with respect to sensitivity accompanied with high and sharper response was been obtained with these pH values.…”

“…Wang et al. have stated that ZrO 2 demonstrated exceptional conductivity, providing large surface area when utilized in mixtures. So, It shows an interesting enactment in heterogeneous catalysis and sensing.…”

“…Generally, ZrO 2 has been utilized in various requests like sensing and catalysis [15] owing to its unique properties. Wang et al [18] have stated that ZrO 2 demonstrated exceptional conductivity, providing large surface area when utilized in mixtures. So, It shows an interesting enactment in heterogeneous catalysis and sensing.…”
