| 英文摘要 | Cobalt-doped manganese octahedral molecular sieves with an ordered cryptomelane structure (OMS-2) were synthesized by a one-step hydrothermal method. The cobalt precursor was directly added into the solution before crystallization to allow its incorporation into the mixed-valent framework of K-OMS-2. The structure, redox properties, and surface hydrophobicity of Co-doped K-OMS-2 were examined by X-ray diffraction, FTIR spectroscopy, Raman spectroscopy, SEM, TEM, N-2 sorption, temperature-programmed reduction by H-2, X-ray photoelectron spectroscopy, and water contact-angle system. The incorporation of Co induced a morphological change in K-OMS-2 from nanorods to nanofibers and an increase in the specific surface area from 70.6 to 188.3m(2)g(-1). Co-doped K-OMS-2 was shown to be able to completely convert CO at 100 degrees C in the presence of approximately 3% water vapor. The promotion effect of Co on the catalytic activity is believed to originate from the enhanced redox capacity and surface area of K-OMS-2, whereas the improved surface hydrophobicity may induce superior water-tolerant performance. |
