In this study, we introduce a highly effective non-metallic iodine single-atom catalyst (SAC), referred to as I-NC, which is strategically confined within nitrogen-doped carbon (NC) scaffold. This configuration features distinctive C-I coordination that optimizes the electronic structure of nitrogen-adjacent sites. As result, arrangement enhances electron transfer from peroxymonosulfate (PMS) active sites, particularly electron-deficient carbon. followed by deprotonation process generates radical (SO5•-). Subsequently, SO5•- undergoes disproportionation reaction, leading production singlet oxygen (1O2). Furthermore, energy barrier for rate-limiting step generation in I-NC significantly lower at 1.45 eV, compared 1.65 eV NC reduction effectively overcomes kinetic obstacles, thereby facilitating an enhanced 1O2. Consequently, exhibits remarkable catalytic efficiency and unmatched reactivity PMS activation. leads accelerated degradation pollutants, evidenced relatively high observed rate constant (kobs ~ 0.436 min-1) other metallic SACs. study offers valuable insights into rational design SACs, showcasing their promising potential Fenton-like reactions water treatment applications.
