Single atom site catalysts (SACs) with atomically dispersed active sites can be expected to potential ideal for accurately modulating the persulfate activation pathway during water remediation process because of their well-defined structure and maximum metallic utilization. In this paper, a series Cu SACs different coordination environments were synthesized elaborately regulate peroxymonosulfate in AOPs clarify species generation transformation remediation. The degradation rate constants (kobs) Cu-N2, Cu-N3, Cu-N4 0.028, 0.021, 0.015 min–1, respectively. Cu-N2 exhibited noticeable enhanced performance bisphenol A (BPA) removal from compared that Cu-Nx (x = 3, 4), accompanied by (PMS) variation. As shown experimental theoretical results, PMS was transformed ROS electron transfer nitrogen numbers decreasing 4 2, which ascribed uneven charge distribution as well upshifts d-band center, thereby optimized activation. Furthermore, increasing vacancies single also result more unoccupied 3d orbitals atoms SACs, improving intermediates' (PMS BPA) adsorption–desorption BPA performance. These findings provided beneficial approach number regulation

Rational regulation of the coordination environment single-atom catalysts (SACs) is a promising yet challenging strategy to enhance their activity. Here, we introduce an O atom into second shell Co–N4 sites via simple thermal treatment, forming Co–N4–ON matrix boost photosynthetic hydrogen peroxide (H2O2) production. This modification significantly alters electronic structure Co site, bringing d-band center closer Fermi energy and elevating conduction band Co–N4–CN its reducing capacity. Density functional theory (DFT) calculations reveal intensified charge redistribution reduced work function in Co–N4–ON, facilitating O2 adsorption. Notably, exhibits lowest adsorption energy, indicating stronger interaction between Co–N4–O O2, which further strengthened by orbital hybridization transfer at interface, leading enhanced activation. The optimized catalyst demonstrates superior reduction capabilities with barrier during H2O2 desorption. Consequently, it achieves production rate 3098.18 μmol g–1 h–1 under neutral conditions, 2.6 times higher than that Co–N4–CN. Moreover, maintains 1967.79 over 10 h continuous flow reactor natural sunlight ambient air, highlighting durability practicality. study underscores crucial role SACs offers valuable insights atomic-level structure–activity relationships, thus contributing advancements design for efficient
