以各种有机溶剂为反应介质，采用溶剂热法合成了NbO4(KNbO3)纳米立方体。在不同的醇类和醚类溶剂以及醇类和醚类混合溶剂中进行了溶剂热合成。溶剂热合成的起始原料为氧化Nb和氢氧化钾。X-射线衍射仪(fi)证实了钙钛矿型KNbO_3的存在。用扫描电子显微镜、透射电子显微镜和扫描电子显微镜(STEM)研究了KNbO_3的形貌。用能量色散X射线(EDX)光谱分析了KNbO_3中的元素。KNbO_3纳米立方体的长度与所用溶剂中的烷基链长相同。STEM和EDX分析表明，KNbO_3纳米立方体中存在K、Nb和O三种元素，并且这些元素在整个纳米立方体中分布均匀。
Potassium niobate (KNbO 3 ) nanocubes were synthesized via a solvothermal method using various organic solvents as the reaction medium. The solvothermal synthesis was conducted in different alcohols and ether-type solvents, and in mixtures of alcohol and ether-type solvents. The starting materials for the solvothermal synthesis were niobium oxide and potassium hydroxide. X-ray diffraction con fi rmed the presence of perovskite-structured KNbO 3 . The morphology of KNbO 3 was investigated using scanning electron microscopy, transmission electron microscopy, and scanning transmission electron microscopy (STEM). Energy-dispersive X-ray (EDX) spectrometry was used to determine the elements present in the KNbO 3 . The KNbO 3 nanocubes were the same length as the alkyl chain in the solvent that was used. The STEM and EDX analyses indicated that three elements, potassium, niobium, and oxygen, were present in the KNbO 3 nanocubes, and that these elements were distributed homogeneously throughout the nanocubes.
