采用水热法成功制备了具有良好立方结构、粒径小于10 nm、在非极性有机溶剂中高度分散的钛酸锶（SrTiO 3）纳米粒子。水溶性钛配合物和氢氧化锶被用作前体。当在没有油酸的情况下进行HT过程时，所获得的SrTiO 3颗粒相对较大并且聚集。然而，SrTiO 3纳米立方体是高度分散在己烷中，通过HT过程中使用油酸和肼。
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 hydrothermal (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.
