The invention relates to a novel method for removing indoor formaldehyde by nano manganese dioxide. The method comprises the following steps: KMnO4 and MnSO4 are subjected to synthesis to obtain MnO2 at normal temperature, other metal ions are doped, and different metals-doped nanocapsule MnO2 spheres can be obtained. From the research result, the metal-supported nano MnO2 has a following sequence for oxidizing catalytic activity of formaldehyde under low temperature: Ag/MnO2 is greater than Cu/MnO2, Cu/MnO2 is greater than Zn/MnO2. A catalyst is composed for minimal rod-shaped object with average diameter of 40 nm.
