Mesoporous Mn-based multi-component metal oxide for fast chemical warfare agent degradation

Protection against harmful chemical compounds is a major social concern, especially warfare agents (CWAs) that are easy to synthesize and can cause mass casualties. The metal oxides with large surface area, porous structures, number of active sites have shown outstanding performance for the adsorption decontamination CWAs. However, single-component show lower degradation rate agents. Here, we demonstrate convenient homogeneous hydrolysis method synthesis mesoporous manganese-based multi-component oxides. Our strategy enables Ce or/and Zr be doped into δ-MnO2 structure during forming process, remarkably enlarging area providing rich CWA catalysis. as-synthesized exhibit excellent degradation. It surprising find best degree removal mustard gas (HD), soman (GD), VX nerve agent (VX) 90.60%, 87.32%, 100%, respectively, reaction samples in 4 h, 2.92-fold increase HD, 8.28-fold GD, 1.67-fold contrast undoped δ-MnO2. This work may provide an avenue developing new generation materials other catalysts.
