高温液相醇解法制备钴纳米粒子

Preparation of Cobalt Nanoparticles by High Temperature Liquid Phase Diol Reduction Method

摘要: 利用1,10-癸二醇做还原剂,在油酸和乙二醇辛基苯基醚两种表面活性剂存在下制备出磁性钴纳米粒子,利用XRD、XPS、TEM和激光光散射仪对所制备的钴纳米粒子进行了表征.结果表明:该方法制备的钴纳米粒子具有hcp相,平均粒径大约为30nm.

Abstract: 1,10-decandiol was used as reducing agent to synthesize magnetic cobalt nanoparticles with the surfactants of oleic acid and ethylene glycol octyl phenyl ether(OP).The structure and valency state of cobalt nanoparticles were measured by XRD and XPS.The morphology was surveyed by TEM and laser particle size detector respectively.The cobalt nanoparticles consisted of hcp phase and the average size was about 30nm.
