Strain‒induced spin regulation of stepped Co(111) for boosting peracetic acid magnetocatalysis

for sulfamethoxazole abatement and thus attain high-effective greener decontamination for water remediations. Spin‒polarized density functional theory and experimental results collectively confirm strain-induced spin modulation at Co(111) step A sites as a critical reactivity determinant. This work integrates MF into PAA utilization and thus provides a perspective on improving the atomic economies of developing ferromagnetic nanoparticulated metal sites into water remediation in low-energy utilization route.
