摘　　要：具有众多优良性能的SrTiO_(3)已经受到人们的广泛关注。钛酸锶光催化剂能够在光子的激发下生成强氧化性的羟基自由基和超氧离子自由基等,进而有效地降解废水中有机物。然而,SrTiO_(3)作为光催化剂,具有对可见光利用率小、难回收等问题。针对此问题,分析了相关文献中关于制备和改善SrTiO_(3)性能的方法,总结了复合高吸附性材料、复合半导体、掺杂元素、改善结构、建立特定制备方法和复合可回收材料对SrTiO_(3)光催化剂的性能影响和改性方法,并对今后的研究发展方向提出展望。Strontium titanate(SrTiO_(3))has attracted extensive attention due to their numerous excellent properties.SrTiO_(3) photocatalyst can generate strong oxidizing hydroxyl radical and superoxide ion radicals under the excitation of photons,and then degrade organic matter in wastewater effectively.However,as a photocatalyst,SrTiO_(3) has low utilization rate of visible light and is difficult to recycle.Aiming at this problem,this paper analyzed the methods for the preparation and performance improvement of SrTiO_(3) performance in the related literature,summarized the effects of composite high adsorption materials,compound semiconductor,doping elements,structure improvement,establishment of specific preparation methods and composite recyclable materials on the properties of SrTiO_(3) light catalyst and the modification methods,and put forward prospects for the research directions in the future.
