Progress of controllable synthesis of rare-earth containing perovskite nano-materials

近年来,钙钛矿纳米材料在能源相关领域得到了迅猛发展,这得益于其优异的光电、催化等性能.稀土元素因其特殊4f电子构型相关的性质而被当作掺杂剂或组成元素来调控钙钛矿纳米材料的性能,拓展钙钛矿材料在诸多领域的应用.基于此,本文对近年来稀土钙钛矿纳米材料的可控合成方法进行了总结,并以卤化物型和氧化物型稀土钙钛矿的零维、一维、二维和三维纳米材料为实例,论述了不同形貌纳米材料的制备方案,并对稀土钙钛矿纳米材料的发展前景给予了展望.

Perovskite nano-materials have been rapidly developed in energy-related subjects due to their excellent photoelectric magnetic and catalytic performances in recent years.Rare-earth(RE)elements with special 4 f electron configuration related properties have been widely used as dopants or components in perovskite nano-materials to improve their performances and broaden their applications.Based on this,this work summarizes the controllable synthesis of RE containing perovskite nano-materials in last decades and discusses the classical preparation methods of zero-dimensional,one-dimensional,two-dimensional and three-dimensional morphologies of perovskite nano-materials.According to the different morphologies of RE-containing halide and oxide nano-perovskites,the feasible synthetic approaches are reviewed.The development of RE-containing perovskite nano-materials is also prospected.
