Abstract

The Co−Mn mixed metal oxide was firstly fabricated using Co(NO₃)₂, KMnO₄ and K₂CO₃. The tuned catalysts, donated as xM-Co₃Mn₁ (x=0, 0.025, 0.05 and 0.1), were synthesized by selective dissolve method (SD). The physicochemical properties induced by different acid concentrations on catalysts were explored via a series of characterization techniques. Compared with the original material, the catalysts treated by SD had higher advantages in enriching crystal defects, surface Co²⁺ and adsorbed oxygen species as well as increasing the specific surface areas (SSA). Among acid-treated catalysts, 0.05 M-Co₃Mn₁ exhibited the best catalytic activity, while the T₅₀ and T₉₀ were 71 and 117 °C lower than the original one. Meanwhile, 0.05 M-Co₃Mn₁ showed excellent stability and great regeneration ability.
