Sub-10 nm strontium titanate nanocubes highly dispersed in non-polar organic solvents

摘要

Strontium titanate (SrTiO3) nanoparticles with well defined cubic shape and sub-10 nm size that are highly dispersible in non-polar organic solvents were successfully synthesized by hydro thermal (HT) processing. Water-soluble titanium complexes and strontium hydroxide were employed as precursors. When the HT process was carried out without oleic acid, the SrTiO3 particles obtained were relatively large and aggregated. However, SrTiO3 nanocubes that are highly dispersible in hexane were obtained via the HT process using oleic acid and hydrazine.
