“…Previous studies reveal that surface CO groups in carbon materials are the active sites for PMS activation to generate 1 O 2 through a ketone‐catalyzed process. [ 25–27 ] In this work, the high‐resolution O1s XPS spectra also confirm the existence of surface CO as well as C–O groups in the carbon spheres (Figure S15, Supporting Information). However, the core–shell sphere (CS‐3 and CS‐4) showed a higher ratio of surface CO groups but lower performance than those of the hollow spheres (CS‐1 and CS‐2) (Figure S15, Supporting Information), indicating that the performance of the carbon spheres might not be solely dominated by the surface oxygen groups.…”

“…PMS oxidation by Co‐SA involved the formation of 1 O 2 . When electrons were released from the PMS, a corresponding PMS anion radical (SO 5 .− ) was produced [18] . Meanwhile, Co 3+ on the surface of Co‐SA was reduced by PMS.…”
