摘　　要：铈基氧化物在催化、防腐、光催化、紫外吸收剂、光学器件、隔热涂层和玻璃磨料等领域有着广泛的应用。这主要是由于铈的独特的电子结构和纳米尺度上的尺寸效应使得这些材料的技术应用是可调控的。铈氧化物表面的Ce(Ⅲ)和Ce(Ⅳ)氧化态之间的可逆转化过程对铈氧化物材料的功能和潜在用途是至关重要。本文在国内外完成的研究基础上,综述了铈基氧化物涂料的主要制备方法与技术应用的研究进展。Cerium-based oxides are widely used in catalysis,anticorrosion,photocatalysis,UV absorbent,optical devices,thermal coatings and glass abrasives.This is mainly due to the unique electronic structure of cerium and the size effect on the nanometer scale.The reversible conversion process between the oxidation states of Ce(Ⅲ) and Ce (Ⅳ)on the surface of cerium oxide is very important for the functional and potential uses of cerium oxide materials.In this paper,the main preparation methods and application of cerium-based oxide coatings are reviewed based on the work done to date.
