Abstract

ZnO/Co3O4 porous nanocomposites were successfully fabricated by the thermal decomposition of Prussian Blue analogue (PBA) Zn3[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 °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.
