N2 - Meso-structured polycrystalline MCo2O4(4.5) (M = Mn, Ni, Fe, Cu) spinels have been successfully fabricated through one-pot pyrolytic method using homogeneous complex oxalates as precursors. In such a protocol, the pyrolysis products, nano-sized spinel crystallites, connected together to form mesoporous structure. Compared with that through nano-casting method, this strategy is much facial and efficient, and resulting material MnCo 2O4.5 calcined at 250 °C possesses much higher specific area, excellent catalytic activity and stability for CO oxidation at ambient temperature. The full CO conversion can be achieved at as low as 30°C.
