【摘要】 以TiO2和NaCl为原料,在非离子表面活性剂NP-9作用下通过简单的熔盐法在相对较低的温度(825℃) 下制备了Na2Ti6O13单晶纳米带。制备的纳米带的宽度为10-15nm,长度为数十μm。通过选区电子衍射方法 (SEAD)和透射电子显微镜对纳米带的微观结构进行了详细的表征。本文的研究为其它三元氧化物一维结构的制备提供了一种新的思路。更多还原

【Abstract】 A simple approach to the molten salt synthesis of Na2Ti6O13 nanoribbons from TiO2 and sodium chloride has been realized with the assistance of nonionic surfactant NP-9 at a relatively low temperature of 825℃. Single-crystalline Na2Ti6O13 nanoribbons of widths 15-100 nm and length up to tens of microns have been obtained. Structure of the nanoribbons was identified using selected-area electron diffraction (SAED) and electron microscopy. The facile technique offers an alternative opportunity for the synthesis of other ternary metal oxide 1D nanostructures.更多还原
