Mn-Co mixed oxide nanorod with porous structure and high surface area was fabricated by an oxalate route and further used for deep oxidation of VOCs. Compared to the single MnOx or Co3O4, the Mn-Co mixed oxide showed an enhanced activity for ethyl acetate and n-hexane oxidation with T-90% was low to 194 and 210 degrees C at a high space velocity, respectively. The formation of solid solution with spinel structure inhibits the growth of nanoparticles which leads to its higher surface area, and the strong synergistic effect of Mn-Co species in the oxide makes a great contribution to its low temperature reducibility which plays a key role in VOCs' oxidation.
