制备了表面镀有光催化剂薄膜的自清洁陶瓷，并利用ＸＲＤ、ＡＥＳ和原位光催化反应方法等研究了其光催化降解油酸和灭菌的特性，考察了热处理条件和膜厚度等光催化膜制备与反应条件对自清洁陶瓷光催化活性的影响．研究结果表明，灭菌效果和油酸光降解速度取决于负载光催化膜的晶相组成、晶粒大小及其比表面积．
Self-cleaning ceramic materials were prepared by coating photocatalytic membrane on ceramic matrix. The photocatalytic behavior of these materials
for degradation of oleic acid and sterilization was studied by using XRD, AES, and in-situ reaction techniques. The effect of preparation and reaction
conditions including heating treatment and thickness for the membrane on photocatalytic activity of the self-cleaning ceramics was examined. The
results show that the photodegradation of oleic acid and sterilization of the self-cleaning ceramics are determined by crystal structure,
particle size, and specific surface area of the supported photocatalyst membrane．
