通过草酸盐路线制备了具有多孔结构和高比表面积的Mn-Co混合氧化物纳米棒，并进一步用于VOCs的深度氧化。与单一 MnOxor Co3O4 相比，Mn-Co 混合氧化物在高空速下对乙酸乙酯和正己烷氧化的活性增强，T90% 分别低至 194 和 210 °C。具有尖晶石结构的固溶体的形成抑制了纳米粒子的生长，从而导致其具有更高的表面积，并且氧化物中Mn-Co物种的强烈协同效应对其低温还原性做出了巨大贡献，这在VOCs的氧化中起着关键作用。
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 MnOxor Co3O4, the Mn–Co mixed oxide showed an enhanced activity for ethyl acetate and n-hexane oxidation with T90%was low to 194 and 210 °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.
