Abstract

Potassium titanate (K₂O·nTiO₂, n = 4 or 6) nanostructures were prepared by a sol-gel method. The growth of potassium tetratitanate (K₂Ti₄O₉) and potassium hexatitanate (K₂Ti₆O₁₃) nanorods was obtainable in a range of Ti(OC₂H₅)₄/CH₃OK molar ratio from 1 to 2 and heating temperature from 800 °C to 950 °C with different morphologies and size distributions of the products. The role of pre-crystallized K₂O phase on the growth behavior of K₂O·nTiO₂ (n = 4 or 6) nanostructures was demonstrated by structural and morphological observation.
