摘要/Abstract

摘要： 以燃烧法制备氧化锌并以其为包裹对象用沉淀法合成ZnO/CeO₂复合氧化物,采用XRD、SEM 、IR、TG-DTA、UV-Vis、TEM对样品进行表征,结果表明氧化铈以包覆形式与氧化锌形成复合氧化物。用改性剂对复合氧化物进行改性研究,以亲油化度考察改性剂的类型、改性剂的用量、改性温度、pH值对改性效果的影响。实验结果表明:当选用硬脂酸钠为改性剂且用量为ZnO/CeO₂的4%,改性温度为60℃,pH值为7时,样品粒径明显变小,分散性变好,亲油化度明显提高,可获得最佳改性效果。

Abstract: Zinc oxide was prepared by the combustion method.ZnO/CeO₂ composite oxides were synthesized by the precipitation method with zinc oxide as the coated object.The samples were characterized by XRD,SEM,IR,TG-DTA,UV-Vis and TEM.ZnO was coated by CeO₂ and composite oxides were formed.The composite oxides were modified with modifier reagent,and modification effect was evaluated by the degree of oil-affinity.The type of modifier,mass ratio of modifier,reaction temperature and pH value of solution were studied.The optimal reaction conditions were as follows:modifier stearate,temperature 60℃,mass ratio of modifier 4% of composite oxides,pH value of solution 7.Particle size became smaller,dispersion of samples was better and the degree of oil-affinity of sample was improved after the samples were modified.

Key words: ZnO/CeO₂, composite oxides, modification
