[0048] The present invention also provides a kind of Ag-Ag described in the above technical scheme 2 The preparation method of Se composite nanotube, comprises the following steps:
[0049] Under stirring conditions, Ag nanowires, ZnSe-Amine organic-inorganic hybrid nanomaterials and acid solution are mixed and reacted to obtain Ag-Ag 2 Se composite nanotubes.
[0050] In the present invention, the Ag nanowires serve as templates. The present invention has no special limitation on the source of the Ag nanowires, and the Ag nanowires well-known to those skilled in the art can be used. Technical proposals are self-prepared. In the present invention, Ag nanowires are preferably prepared according to the synthesis method reported in literature (Advanced Materials, 2011, volume 23, pages 3052-3056).
[0051] The present invention has no special limitation on the type and source of the ZnSe-Amine organic-inorganic hybrid nanomaterial, and the ZnSe-Amine organic-inorganic hybrid ...
Embodiment 1
[0059] According to this embodiment figure 1 The route shown to prepare Ag-Ag 2 Se composite nanotubes, figure 1 The reaction schematic diagram of the preparation method provided by the present invention:
[0060] In Example 1, Ag nanowires were prepared according to the synthesis method reported in the literature (Advanced Materials, 2011, Volume 23, Pages 3052-3056);
[0061] The obtained solid product sample Ag nanowires were characterized by JEOLJEM-2011 transmission electron microscope (TEM), ShimadzuUV-240 ultraviolet absorption spectrometer, and PW1710 X-ray diffractometer (XRD).
[0062] figure 2 The transmission electron microscope TEM picture of the Ag nanowire prepared for Example 1 of the present invention, from figure 2 It can be seen that the statistical diameter of the Ag nanowire is 55nm; image 3 The ultraviolet-visible light (UV-vis) absorption spectrum of Ag nanowire and Ag-AgSe composite nanotube prepared for the embodiment of the present invention 1...
Embodiment 2
[0073] Synthesis of Ag-Ag Using Nitric Acidified Slow-release Se Source 2 Se composite nanotubes:
[0074] In 40mL deionized water, add 0.075mmol [ZnSe](DETA) 0.5 Nanosheets, stirred evenly by magnetic force, added 24mg of Ag nanowires according to the ratio of atomic molar ratio Ag:Se=3:1, after stirring evenly, added 0.2mL nitric acid, the mass fraction of nitric acid was 69%, and reacted for 6 days. Carry out at room temperature, maintain strong and continuous (>700rpm) magnetic stirring to obtain Ag-Ag 2 Se composite nanotube; the Ag-Ag 2 The middle of the Se composite nanotube is hollow, the inner layer is Ag nanotube and the outer layer composited on the surface of the inner layer is Ag 2 Se layer.
[0075] The present invention respectively adopts JEOLJEM-2011 transmission electron microscope (TEM, HRTEM, EDS), PW1710X-ray diffractometer (XRD) to the gained solid product sample Ag-Ag 2 Se composite nanotubes were characterized.
