| 中文摘要 | molybdenum trioxide nanobelts and prism-like particles with good crystallinity and high surface areas have been prepared by a facile hydrothermal method, and the morphology could be controlled by using different inorganic salts, such as kno3, ca(no3)(2), la(no3)(3), etc. the possible growth mechanism of molybdenum trioxide prism-like particles is discussed on the basis of the presence of hi and the modification of metal cations. the as-prepared nanomaterials are characterized by means of powder x-ray diffraction (pxrd), field-emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), high-resolution tem (hrtem), fourier transformation infrared spectroscopy (ft-ir), x-ray photoelectron spectroscopy (xps), and ultraviolet and visible spectroscopy (uv-vis). tem and hrtem micrographs show that the molybdenum trioxide nanobelts and prism-like particles have a relatively high degree of crystallinity and uniformity. bet specific surface areas of the as-prepared molybdenum trioxide nanocrystals are 67-79 m(2)g(-1). xps analysis indicates that the hexavalent molybdenum is predominant in the nanocrystals. uv-vis spectra reveal that the direct band gap energy of the annealed molybdenum trioxide prism-like particles shows a pronounced blue shift compared to that of bulk moo3 powder. |
