一种纳米结构氧化铈及其应用
摘要：
本发明涉及一种纳米结构氧化铈及其应用，属于无机纳米材料与应用技术领域。本发明的纳米结构氧化铈采用化学共沉淀法于室温下制得；然后在刚果红染料废水中加入纳米结构氧化铈，降解刚果红染料废水。本发明的纳米结构氧化铈的制备无需高温高压的苛刻实验条件，成本低廉，工艺简单，在制备过程中不引入其他污染物，获得的纳米结构氧化铈廉价且纯度高。纳米结构氧化铈材料作为催化剂在常温常压下降解刚果红染料废水，有效解决了降解刚果红染料废水的催化剂工艺复杂、降解条件要求苛刻、处理效果不明显、成本较高、存在二次污染的问题。
摘要（英）：

The invention relates to nano-structured cerium oxide and applications thereof and belongs to the technical field of inorganic nano-materials and applications. The nano-structured cerium oxide is produced at room temperature by chemical coprecipitation process. The nano-structured cerium oxide is added to a waste liquid of Congo red dye to degrade the waste liquid of Congo red dye. The preparation of nano-structured cerium oxide doesn't need the harsh experimental conditions such as high temperature and high pressure, has a low cost and a simple process, and doesn't adopt other pollutants in the preparation process. The product of nano-structured cerium oxide has a low price and a high purity. The nano-structured cerium oxide material is used as a catalyst to degrade the waste liquid of Congo red dye at room temperature and normal pressure, so as to effectively solve the problems during the degradation of the waste liquid of Congo red dye, such as complex process of catalysts, harsh requirements for degradation conditions, poor treatment effect, high cost and secondary pollution.
