摘　　要：光催化氧化技术是近年来国内外的一个热点研究领域,具有良好的应用前景.钙钛矿型氧化物由于其结构的稳定性和特殊的物化性能,日益成为光催化材料研究领域的重要课题.文中详细评述了钙钛矿型光催化剂的常用表征技术(XRD,XPS,TEM,UV-Vis DRS,BET等)和制备方法,重点对其中的传统高温固相法、溶胶-凝胶法以及水热法进行了分析.最后,提出了非金属元素掺杂改性钙钛矿型氧化物光催化剂是今后的一个重要研究方向,并存在巨大的研究空间.The research on photocatalytic oxidation technology has been one of the most important issues in recent years and has bright prospect in the future. Perovskite-type oxides have become the study-hotspot of photocalytic materials due to their stable structure and unique physical and chemical properties. The characterization technologies （XRD, XPS, TEM, UV- Vis DRS, BET, etc. ） and preparation methods are reviewed in the paper. The conventional high temperature solid-state reac- tion method, sol-gel technique and hydrothermal method are specifically introduced. Finally, the nonmental element doping method of modifing perovskite-type oxides is also proposed, which is regarded as an important research direction, having an e- normous research space in the future.
