| 摘 要： | 用溶剂热和水热联用方法合成了尺寸可控的立方形Co_3O_4纳米材料,研究了Co_3O_4纳米材料的形貌、组成、结构和表面等离子共振特性.研究表明:合成的纳米材料具有立方形的几何形状和尖晶石纯立方相的晶体结构,而且它们的尺寸(立方形的边长)随Co(NO_3)_2浓度的增加(1～6 mmol)由约10 nm增加到约36 nm;研究也发现不同形状的Co_3O_4纳米材料具有不同的表面等离子共振性质,与空壳的Co_3O_4纳米球相比,立方形的Co_3O_4纳米材料具有更好的表面等离子共振性能.

| Abstract: | Cube-shaped Co3O4 nanoparticles were synthesized through the combination of solution-phase route and hydrothermal route,whose sizes could be effectively controlled. composition,geometrical and crystalline structures and surface plasmon resonance property of the Co3O4 nanoparticles were investigated. Results show that the as-prepared Co3O4 nanoparticles possessed a cube shape and a pure spinel cubic crystal phase and their sizes gradually increased from ca. 10 nm to ca. 36 nm with increasing the concentratio... |
