【Abstract】 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 MnO_x powder under the same conditions,which demonstrates that the catalytic activity is closely related to the morphology of the catalysts.更多还原
