A facile bottom-up method for the synthesis of lithium titanate nanoplates using a peroxo titanium complex ion precursor is reported. Instead of employing complicated treatment with high alkali concentration, the self-organization reaction between lithium and titanium ions in the prepared ion precursor can enable the formation of layered lithium titanate crystals (LiHTiO, where = 0.1 and 1.52 for as-synthesise and acid-treated samples, respectively) under low alkaline conditions. We demonstrate that layered lithium titanate crystals can be grown anisotropically into individual nanoplates. Our work presents an easy and useful platform for the production of titanate materials with various morphologies based on the interaction with ionic species.
报道了一种使用过氧钛络合离子前驱体合成钛酸锂纳米片的简便自下而上方法。该方法无需采用高碱浓度的复杂处理，所制备的离子前驱体中锂和钛离子之间的自组装反应能够在低碱条件下形成层状钛酸锂晶体（LiHTiO，合成样品和酸处理样品的 分别为 0.1 和 1.52）。我们证明层状钛酸锂晶体可以各向异性生长为单个纳米片。我们的工作基于与离子物种的相互作用，为生产具有各种形态的钛酸盐材料提供了一个简便且有用的平台。
