Efficient peroxymonosulfate activation by magnesium-doped Co₃O₄ for thiacloprid degradation: regulation of Co²⁺/Co³⁺ ratios and degradation mechanism.

ABSTRACT: AS a low-cost and high-performance catalyst, spinel cobalt oxide (Co₃O₄) has two different catalytic active sites (tetrahedral Co²⁺ and octahedral Co³⁺) to drive the activation of peroxymonosulfate (PMS) through Co²⁺/Co³⁺ redox cycle. Tuning Co²⁺/Co³⁺ atomic ratio on the surface of Co₃O₄ for the construction of a synergy in the Co²⁺/Co³⁺ redox cycle might be an effective way to further boost PMS activation performance of Co₃O₄ catalyst. Herein, we suggested a metal-doping strategy to regulate Co²⁺/Co³⁺ atomic ratio of Co₃O₄ by partially substituting Co²⁺ with inert Mg²⁺ and
