Abstract
Advanced oxidation processes (AOPs) are among the most effective technologies for environmental remediation, particularly in removing recalcitrant organic pollutants from water. Carbon-based single-atom catalysts (CSACs) combine the strengths of both heterogeneous and homogeneous catalysts and maximize metal utilization via isolated metal active sites, thus fine-tuning the catalytic efficiency in AOPs via engineering molecular architecture. Atomically dispersed metal atoms are usually stabilized through ionic or covalent interactions with neighboring atoms, thus the geometric and electronic properties of CSACs are significantly affected by their local microenvironment. In this review, we explored recent advances in CSAC synthesis, emphasizing both bottom-up and top-down strategies, with a focus on microenvironment modulation. We also discussed the local microenvironment regulation of CSACs in AOPs, considering factors such as the first coordination sphere (metal center choice, site spacing/density and coordination structure) and the medium to long-range coordination (bimetallic doping, heteroatom doping/defect engineering and interface coupling). Finally, we outlined the challenges and prospects of CSAC microenvironment engineering, providing insights for advancing CSACs development in AOPs and beyond.
