钙钛矿型氧化物由于其结构的稳定性和特殊的物化性能,日益成为材料科学领域的研究热点.但是其催化活性偏低,尤其是带隙能较高,不能高效吸收太阳光谱中丰富的可见光,限制了该技术的推广.利用金属元素掺杂改性钙钛矿型氧化物是有效改善其光催化性能的方法之一.目前利用金属元素掺杂改性钙钛矿型氧化物光催化剂的制备方法主要有溶胶-凝胶法、水热法、固相反应法及微乳液法等,对其表征技术TEM,SEM,XRD,XPS,UV-Vis DRS等进行了评述,并重点介绍了金属元素掺杂对钙钛矿型氧化物光催化性能的影响.最后,提出了综合利用金属和非金属掺杂的功效,通过对钙钛矿型氧化物进行金属和非金属双组分复合掺杂改性,制备在可见光区具有高光催化活性的纳米催化剂是该研究领域的发展方向,并存在巨大的研究空间.
