Bimetallic spinel oxides are efficient catalysts for peroxymonosulfate (PMS) activation but the catalytic mechanism is unclear. The critical role of Mn−O covalency in determining the intrinsic activity of Co 3−x Mn x O 4 and a new mechanism of Co–Mn synergy are revealed by Wen‐Wei Li and co‐workers in their Research Article on page 274. Co strengthens Mn−O covalency in the octahedral configuration of Co 3−x Mn x O 4 , which lowers the charge transfer energy of the Mn Oh –PMS interaction and drastically accelerates Mn VI /Mn III redox cycling.
