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.
