摘　　要：压电催化和光催化的耦合被称为压电光催化,作为处理废水最有效的工艺之一,压电光催化在降解有机污染物和微生物消毒方面引起了人们的广泛关注。但是,传统的压电光催化材料往往含铅,其造价昂贵且容易造成二次污染,因此,研究者们在不断探索新型压电材料来驱动压电催化过程。钛酸钡(BaTiO3)作为一种典型的压电半导体材料,其制备成本低、压电活性强、具有优异的压电催化性能,已被广泛用于水分解制氢、二氧化碳还原、细菌消毒和废水处理等多个领域。然而,现有钛酸钡材料存在光生载流子分离率低等问题,实际制备过程中往往需要对其性能进行改进和优化。在此基础上,对BaTiO3的晶体结构、压电光催化原理、极化方式、薄膜制备方法进行了综述,并展望了其未来发展趋势。The coupling of piezoelectric catalysis and photocatalysis is called piezoelectric photocatalysis.As one of the most effective processes for wastewater treatment,piezoelectric photocatalysis has attracted extensive attention in the degradation of organic pollutants and microbial disinfection.However,the traditional piezoelectric photocatalytic materials often contain lead,which is easy to cause secondary pollution.Therefore,researchers are constantly exploring new piezoelectric materials to drive the piezoelectric catalytic process.As a typical piezoelectric semiconductor,BaTiO3 has been widely used in many fields,such as hydrogen production through water decomposition,carbon dioxide reduction,bacterial disinfection and wastewater treatment,because of its low cost,strong piezoelectric activity and excellent piezoelectric catalytic performance.However,barium titanate has several problems,such as low photogenerated carrier separation rate,so its properties often need to be improved and optimized in the actual preparation process.On this basis,the principle,polarization mode,thin film preparation method and research progress of BaTiO3 piezoelectric photocatalysis are reviewed and its future development trend is prospected.
