Hydrothermal treatment of nanoanatase with alkali and alkaline earth hydroxides
Apstrakt
Nanoanatase powder was hydrothermally treated with LiOH, NaOH, KOH or
Ca(OH)2 at T = 120 ºC for 8 h. In all cases, the molar TiO2 : hydroxide ratio was
identical. The obtained samples were washed with distilled water, centrifuged and dried at room temperature. Characterization of the samples was done by X-ray
powder diffraction, TG/DTA/DSC and SEM analysis. Nanoanatase showed very
diverse reactivity toward different alkali and alkaline earth cations. The final
products showed different phase composition, crystallinity and microstructure. With
Li+
and Ca2+ anatase forms different titanate structures while with Na+
and K+
it
mainly retain original anatase structure.
