Double-Confined Ultrafine Cobalt Clusters for Efficient Peroxide Activation.

ABSTRACT: The construction of highly active catalysts presents great prospects, while it is a challenge for peroxide activation in advanced oxidation processes (AOPs). Herein, we facilely developed ultrafine Co clusters confined in mesoporous silica nanospheres containing N-doped carbon (NC) dots (termed as Co/NC@mSiO₂) via a double-confinement strategy. Compared with the unconfined counterpart, Co/NC@mSiO₂ exhibited unprecedented catalytic activity and durability for removal of various organic pollutants even in extremely acidic and alkaline environments (pH from 2 to 11) with very low Co ion leaching. Experiments and density functional theory (DFT) calculations proved that Co/NC@mSiO₂ possessed strong peroxymonosulphate (PMS) adsorption and charge transfer capabili
