Embodiment 1
[0018] Example 1: Precursor for preparing mesoporous nanoribbons with oriented zinc oxide particles
[0019] Mix 0.1M zinc acetate aqueous solution with 0.1M hydrazine hydrate or 0.1M ethylenediamine aqueous solution in the same volume, the original clear solution becomes cloudy immediately, after stirring evenly, let it stand at room temperature for 2 hours, a large amount of flocculent After centrifugation, the precipitate was collected and dried to obtain a solid product.
[0020] The structure, chemical composition and morphology of the solid product were characterized by X-ray diffraction, chemical composition analysis and transmission electron microscopy.
[0021] Fig. 1 is the X-ray diffraction pattern of the product of the present embodiment. The abscissa of the spectrum is the 2θ angle, and the ordinate is the relative intensity of diffraction. However, there is no powder diffraction card corresponding to all the diffraction peaks in the spectrum in the JCPDS powder...
Embodiment 2
[0026] Example 2: Preparation of one-dimensional mesoporous nanobelts with oriented zinc oxide particles from precursors
[0027] Calcining the precursor of the mesoporous nanoribbons of oriented zinc oxide particles obtained in Example 1 at 700° C. in air for 3 hours, a white solid product can be obtained.
[0028] The structure and morphology of the white solid product were characterized by X-ray diffraction, transmission electron microscopy and electron diffraction:
[0029] Fig. 2 is the X-ray diffraction pattern of the product of this embodiment. The abscissa of the spectrum is the 2θ angle, and the ordinate is the relative intensity of diffraction. Comparing the spectrum with the powder diffraction card JCPDS 01-1136, all the diffraction peaks in the spectrum can correspond to the powder diffraction card JCPDS 01-1136, which proves that the product is hexagonal phase zinc oxide. It can be seen from the spectrum that, except for the diffraction peak of zinc oxide, no ot...
