摘要
介绍了 LaBO3的结构特征、合成方法对其理化性质的影响和LaBO3活化PS的作用机制;综述了近几年采用A/B位离子掺杂、金属氧化物负载和碳基材料负载方法改性LaBO3的研究进展;展望了 LaBO3/PS体系降解有机污染物未来的研究方向.提出改性LaBO3的结构稳定性有待进一步改善,需重点研究金属离子浸出的污染影响;进一步研究离子共掺杂改性对LaBO3催化性能的影响;深入研究LaBO3/PS体系降解有机污染物的作用机制等.
Abstract
The structural characteristics of LaBO3,the influence of synthesis methods on its physical and chemical properties,and the mechanism of LaBO3 activation of PS are presented.The research progress of LaBO3 modified by A/B site ion doping,metal oxide loading and carbon-based material loading in recent years is reviewed,and the future research direction of LaBO3/PS system for organic pollutant degradation is prospected.It is suggested that:the structural stability of modified LaBO3 should be further improved,and the pollutant effect of metal ion leaching should be investigated.The effect of ion co-doping modifica-tion on the catalytic performance of LaBO3 is further investigated.The degradation mechanism of organic pollutants in the LaBO3/PS system will be studied in detail.
