氧化铜纳米片的水热合成与表征

利用水热法一步制备了形貌均一的氧化铜纳米片,借助场发射扫描电子显微镜、X射线粉末衍射仪和透射电子显微镜分析了产物的形貌和晶体结构;并研究了反应物浓度及表面活性剂等因素对氧化铜纳米结构的影响.结果表明,以氢氧化钠作为碱源时,在不添加任何表面活性剂的情况下,随着氢氧化钠浓度的升高,纳米片的尺寸减小、厚度增大;此外,通过添加不同的表面活性剂可以得到不同形貌的氧化铜纳米结构.

Hydrothermal synthesis and characterization of cupric oxide nanoflakes

Uniform copper oxide nanoflakes were prepared by one pot hydrothermal method. The morphology and crystal structure of as-synthesized CuO nanoflakes were analyzed using a field-emission scanning electron microscope,an X-ray powder diffractometer and a transmis-sion electron microscope.The effects of the concentration of reactants and the type of surfac-tants on the formation of CuO nanostructures were investigated.Results show that the mor-phology of the product is related to the concentration of NaOH in the absence of any surfactant. With the increase of the concentration of NaOH,the size of the product decreases and its thick-ness increases.Moreover,the morphology of as-prepared CuO product can be adjusted by tun-ing the type of surfactants.
