Surface-Confined Anchoring of Highly Dispersed Nanocobalt Promotes Advanced Oxidation for Eliminating Health-Threatening Organics

with high oxidation potential, which promoted the degradation of POPs. Density functional theory calculations show that nano-Co anchored on NHCSs can spontaneously capture and activate PMS on either a planar carbon matrix or a curved carbon matrix, which is the key to the efficient degradation of POPs by the Co-NHCSs/PMS system. This study not only provides an innovative way to construct nanometal catalysts but also reveals the transformation behavior of PMS on cobalt-based materials, which is of great significance for promoting PMS-based wastewater treatment technology.
