| 中文摘要 | OMS- 2 (2 x 2 type octahedral molecular sieve) and cerium doped OMS- 2 were synthesized by refluxing method. The platinum doped on both samples was prepared by impregnation method for catalytic oxidation of formaldehyde. These catalysts were characterized by BET, XRD, SEM, H-2-TPR and Laser Raman. Results show that OMS- 2 formed needle-shape nanocrystal structure. The addition of Ce before the formation of the OMS- 2 structure obstructs the process due to mismatch of the cation size. Rather than into the framework of the structure, the addition of Pt after the formation of the OMS- 2 structure was loaded on the surface of catalysts, which strongly influenced the bonding of the Mn-O lattice of OMS-2. The properties of the catalyst structure determine the temperature of complete oxidation of HCHO while Pt promotes this reaction at a lower temperature range due to active surface oxygen species and lattice defects. |
