摘　　要：水污染和能源紧缺作为全球性的问题,受到广泛关注。压电催化能够将外部机械能转化为化学能,是一种绿色有效、节能产能的新技术,在解决水污染和能源紧缺问题上具有潜力。然而,简单压电催化体系氧化能力有限,目标污染物多限于水中低浓度易降解有机污染物。针对上述问题,科研工作者采用多种方法强化了压电体系的氧化能力。文章综述了目前常用的三类压电催化强效方法,包括压电材料性能调控、压电-化学药剂耦合、压电驱动方式优化,分析了压电催化技术的能源和环境意义,并对该领域未来的发展方向进行了展望。Water pollution and energy shortage are global problems that are gaining significant attention.Piezoelectric catalysis can convert external mechanical energy into chemical energy.As a green,effective,and energy-saving technology,piezo-catalysis has the potential to solve the above issues.However,the oxidation capacity of a simple piezoelectric system is limited,and the target pollutants are concentrated in degradable organic pollutants with low-concentration in water.To solve the above problems,researchers have employed various methods to enhance the oxidation capacity of the piezoelectric system.Three types of piezoelectric catalytic strengthening methods commonly used were summarized,including regulation of piezoelectric materials,coupling of chemical reagents,and optimization of piezoelectric driving approaches.Besides,the significance of energy and environment as well as the prospects of piezo-catalysis were discussed.
