Summary: In this study, a high-efficiency and stable RuSA-N-C catalyst was synthesized using a solvothermal strategy, which effectively activates PMS for the degradation of organic pollutants. The Ru-N4 sites in RuSA-N-C generate singlet oxygen (1O2) as the main reactive oxygen species for the degradation of Orange II, while the adjacent pyridinic N acts as the adsorption site for anchoring Orange II. The ultra-high catalytic activity of RuSA-N-C is attributed to its distinctive dual reaction sites, which significantly shorten the migration distance from 1O2 to the adsorbed molecules.
