ZnO/Co3O4 Porous Nanocomposites Derived from MOFs: Room-Temperature Ferromagnetism and High Catalytic Oxidation of CO

ZnO/Co3O4 porous nanocomposites were successfully fabricated by the thermal decomposition of Prussian Blue analogue (PBA) Zn-3[Co(CN)(6)](2) nanospheres obtained at room temperature. Interestingly, ZnO/Co3O4 porous nanocomposites exhibit room-temperature ferromagnetism. Moreover, the ZnO/Co3O4 porous nanocomposites show good catalytic activity for CO oxidation, and the CO conversion rate reaches 100% at 250 degrees C. It is suggested that the synergistic effect of each component, relative high surface area (32 m(2) g(-1)) and porous structure lead to the promising catalytic properties.
