利用微波辅助的多元醇法合成出纳米线和海胆状结构Co0.8Ni0.2,采用X射线衍射和透射电镜技术对该材料合成过程中的结构变化进行了详细的研究.根据晶体的成核与生长速率阐述了Co0.8Ni0.2纳米结构的形成机理.结果表明,Co0.8Ni0.2纳米材料在丙三醇氢解反应中的催化性能与其形貌和粒径密切相关.
Co0.8Ni0.2 nanourchins and nanowires were fabricated by microwave-assisted polyol-synthesis.Their structural evolution was monitored by powder X-ray diffraction and transmission electron microscopy measurements.The nucleation and growth rates of the crystah in their formation mechanism were discussed.Their catalytic activity for glycerol hydrogenolysis depended on their anisotropic shape and particle size.
