Peroxymonosulfate (PMS)-based advanced oxidation processes are effective in eliminating health-threatening persistent organic pollutants (POPs), but they require the participation of high-performance catalysts. In this study, a highly dispersed nanocobalt species (Co-NHCSs) was constructed on nitrogen-doped hollow carbon spheres by using double confinement mechanism complexation combined with spatial confinement. The Co-NHCSs/PMS system has high degradation efficiency 95.2% for tetracycline within 30 min, and performance almost not attenuated after repeated use 10 times. can also resist interference complex water environment to achieve efficient POPs multiple scenarios. Reactive oxygen quenching experiments electron paramagnetic resonance confirmed that Co-NHCSs promoted activation PMS into ·OH, SO4·-, 1O2 potential, which POPs. Density functional theory calculations show nano-Co anchored NHCSs spontaneously capture activate either planar matrix or curved matrix, is key system. This study only provides an innovative way construct nanometal catalysts reveals transformation behavior cobalt-based materials, great significance promoting PMS-based wastewater treatment technology.

Air pollution poses a significant challenge to environmental sustainability and inhibits economic social development. In urban areas, the combined effects of high population density, industrial concentration, heat island effect make control even more complex demanding. Most studies on air focus specific sources or localized lacking systematic approach tailored unique conditions megacities. Herein, this study employs bibliometric analysis based Web Science (WOS) Core Collection, incorporating 3109 research articles pollution, including metropolitan areas megacities, published between 2000 2024. By constructing knowledge framework, reveals thematic networks evolutionary trends in field. The findings indicate that key themes, such as aerosols, quality, islands, have emerged focal points. These while relatively distinct, are interconnected, forming three-dimensional framework pollutants–health effects–monitoring, governance. Moreover, disciplinary network exhibits clear convergence trend, with shift from single-discipline interdisciplinary approach. terms international collaboration, bipolar structure led by United States China has taken shape. Through multidimensional identifies hotspots highlights critical role cooperation advancing control. addressing gap cross-disciplinary, multi-perspective research, work enhances overall understanding policies provides valuable insights for promoting global sustainability.
