Effect of process parameters on the synthesis of mesoporous nanocrystalline zirconia with triblock copolymer as template

Nanocrystalline zirconia powders with high surface area, mesoporous structure and tetragonal crystallite phase have been prepared by the surfactant-assisted route by using of Pluronic P123 block copolymer surfactant. The effect of several process parameters such as the type of zirconium precursor, p...

Beschreibung
Zusammenfassung:Nanocrystalline zirconia powders with high surface area, mesoporous structure and tetragonal crystallite phase have been prepared by the surfactant-assisted route by using of Pluronic P123 block copolymer surfactant. The effect of several process parameters such as the type of zirconium precursor, pH value, refluxing time, refluxing temperature and surfactant to zirconium molar ratio on the structural properties of the powders have been investigated.
