摘要
利用乙二醇回流法,以水合肼为还原剂和螯合剂,NiCl2和SbCl3作为反应原料,控制温度在166℃下回流1h,获得了γ-NiSb纳米颗粒.产物用XRD和TEM表征,产品为六方相的纳米颗粒,大小约为40nm.通过对比实验证明了水合肼起了重要作用,并提出了一种可能的反应机理.本方法简单,方便,易于操作,可用于其它纳米材料的制备.
NiSb nanoparticles were synthesized via ethylene glycol （EG） reflux for 1 hour under 166℃, using hydrazine hydrate as chelate agent and reductant, NiCl2 and SbCl3 as source materials. The sample was characterized with X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The results showed that the products were hexaganol phase NiSb nanoparticles with the average size of 40nm. It is supposed that the hydrazine hydrate play important role by comparing experiments. A possible reaction mechanism was proposed. As this method is simple, convenient and easy to be controlled, it may be employed in preparation of other nanomaterials.
