摘要

层状钛酸钠在能源和环境领域的应用极为有利。本文以柠檬酸三钠为Na源，通过低温固相反应合成了亚微米级的层状钛酸钠晶体。包括原位观察在内的表征结果表明，柠檬酸三钠的分解在300-350℃进行，得到的活化Na在520℃及以上的温度下与TiO2反应。因此，本研究为层状钛酸盐材料的合成提供了一种经济可行的方法。

Low-temperature synthesis of submicron-sized layered sodium titanate crystals using citrate salts

Layered sodium titanates are extremely advantageous for use in the energy and environmental fields. Herein, submicron-sized layered sodium titanate crystals were synthesized at low temperatures via solid-state reaction using trisodium citrate as the Na source. Characterization results including in situ observations showed that the decomposition of trisodium citrate proceeded at 300–350 °C, and the resulting activated Na species reacted with TiO2 at temperatures of 520 °C and above. This study therefore provides an economically viable method for the synthesis of layered titanate materials.
