摘要
纳米CeO2具有比表面积大,储氧性能好,负载金属分散度高等许多优良特性,掺杂对CeO2的结构及性能又有进一步改善,因而是目前研究的热点。本文综述了掺杂对CeO2结构的影响,掺杂对CeO2在催化剂方面的应用研究,以及作为阳极材料的研究进展。展望了掺杂对改进CeO2性能的研究方向。
Ceria has been attracted a great deal of attention due to the characteristeristics of high specific surface area,high metal dispersion and good store oxygen.Studied effects of doped elements on structure and properties of ceria are emphases at present.Ceria with doped elements on effect of material structure,on catalyzer and as anode materials was described in detail.With studying progress, ceria with doped elements is prospected in many fields.
