摘　　要：高级氧化法是去除水中有机污染物的常用方法之一.然而,传统的高级氧化法存在电子相互作用弱,有大分子物质干扰,传质过程受限,效率较低等不足.利用空间限域策略,通过构建特定的纳米尺寸反应器,可以有效提升氧化效率.空间限域策略能够实现:(1)优化质子和电荷的迁移;(2)改变分子结构和分子动力学;(3)构建新的活性位点.空间限域常被应用于芬顿氧化、过硫酸盐氧化、光催化氧化、臭氧氧化、电化学氧化等过程.本文总结了空间限域的实现方法和分析方法,归纳了空间限域的三大功能,综述了其在不同氧化过程中的应用,对其在微观和宏观上的效果进行了总结,并对空间限域在高级氧化中的未来发展方向进行了展望.Advanced oxidation processes(AOPs)represent a widely adopted approach for eliminating organic pollutants from water bodies.Nevertheless,conventional AOPs grapple with several challenges,notably including inadequate electron interactions,interference from macromolecular substances,constrained mass transfer processes,and moderate efficiency levels.To overcome these limitations,the employment of a spatial confinement strategy,which entails the construction of tailored nanoscale reactors,has emerged as a promising solution to substantially bolster oxidation efficiency.The spatial confinement strategy offers several key advantages:(1)optimize the migration of protons and charges;(2)alter molecular structures and molecular dynamics;and(3)create new active sites.This strategy is commonly integrated into processes such as Fenton oxidation,persulfate oxidation,photocatalytic oxidation,ozonation,and electrochemical oxidation.This paper summarizes the implementation and analytical methods of spatial confinement,outlines its three major functions,reviews its applications in various oxidation processes,and evaluates its effects at both microscopic and macroscopic levels.Furthermore,future directions for the development of spatial confinement in advanced oxidation are discussed.
