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.

Environmental issues have become more serious these days due to the growth of modern industries. The paper and textile industries, in particular, were heavily dependent on printing discharge dye, which constantly leaked into water ecology constituted a risk public health. Organic wastewater treatment remediation for its associated risks received lot attention lately. This work explored potential g-C3N5 nanostructure as novel photocatalyst malachite green degradation aqueous solution while exposed visible light. nanocomposite was fabricated through an ultrasonicate-assisted technique. A number analysis techniques, such CHNS, XRD, FTIR, UV-DRS, SEM, Electrical, XPS employed verify successful fabrication photocatalyst. At pH 6.5, catalyst dose 0.06 g∙L‒1, with concentration 20 mg∙L‒1, reaction period 90 min, efficiency had been found be 88%. produced hydroxyl radicals (OH•) is considered major scavenger green. above method suggested easy, environmentally friendly practical approach produce excellent photocatalytic 2D nanosheet environmental cleanup.
