钼酸铁/氧化钼异质纳米结构合成制备综合实验设计

Comprehensive experimental design for synthesis of iron molybdate/ molybdenum oxide heteronanostructures

设计了一个综合实验,通过水热法合成氧化钼纳米棒,将其分散到硝酸铁溶液中并经过退火处理后,得到钼酸铁/氧化钼一维异质纳米结构。实验研究了硝酸铁加入量、反应时间以及反应温度等因素对异质纳米结构的影响。实验涉及多种合成方法以及表征测试手段,可以提高学生进行综合实验的能力。

One comprehensive experimental design was described ,in which molybdenum oxide nanorods were first synthesized by a hydrothermal method. The nanorods were dispersed ferric nitrate solution ,and the obtained sample was treated thermally , and finally iron molybdenum oxide/molybdenum oxide heteronanostructures were obtained. In the experiment ,the effects of the addition amount of ferric nitrate , reaction time ,and reaction temperature on the heteronanostructures were investigated. The experiment involved several methods and measured techniques ,which are helpful for students to improve their comprehensive experimental capacity .
