Abstract
Recently,S-scheme heterojunctions have gained considerable attention in the field of photocatalytic en-vironmental remediation as their potential to achieve efficient spatial charge separation coupled with strong redox capacities.Herein,this review provides an overview of the current state-of-the-art in the development of S-scheme-based photocatalysts for the purification of environmental contaminants.The review first covers the fundamentals of heterogeneous photocatalysis for environmental purification.Sub-sequently,an introduction to the background,mechanism,design principles,and characterization tech-niques of S-scheme heterojunctions is presented.Then,the review presents a comparison and summary of using various S-scheme photocatalysts for the removal of several target pollutants,such as bacteria,heavy metals,nitrogen oxides,antibiotics,and phenols.Additionally,the modification strategies of S-scheme heterojunction photocatalysts are also provided.Finally,a brief discussion of the challenges and prospects associated with S-scheme photocatalytic systems is demonstrated.
