摘要： Uniform manganese oxide octahedral molecular sieve (OMS-2) nanorods were synthesized by adding a small quantity of K2S2O8 to the solution containing MnSO4·H2O and KMnO4, and used for complete oxidation of formaldehyde. According to the results of N2 adsorption and X-ray diffraction, the material is a manganese oxide octahedral molecular sieve with the cryptomelane type structure. TEM observation shows that the diameters of the nanorods range from 15 to 25 nm, and the lengths are 300～400 nm. Complete conversion of HCHO to CO2 and H2O can be achieved at 353 K over OMS-2, and the same conversion is obtained at 373 K on the MnOx powder under the same conditions, which demonstrates that the catalytic activity is closely related to the morphology of the catalysts.
