Embodiment Construction

[0013] In order to make the present invention more comprehensible, preferred embodiments are described in detail as follows.

[0014] In the CBD preparation method of Mg-doped ZnO nanorods provided by the present invention, the growth of zinc oxide one-dimensional micro-nano materials is prepared by chemical bath deposition method. Experiments have proved that this method can be prepared by controlling appropriate growth conditions. Undoped and doped ZnO microrod materials are presented.

[0015] A CBD preparation method of Mg-doped ZnO nanorods provided by the present invention specifically includes the following steps:

[0016] Mg 2+ with Zn 2+ Zinc acetate and magnesium acetate with a molar ratio of 1:10 were dissolved in 100 ml of deionized water to prepare a zinc acetate solution. Among them, Mg 2+ The concentration is 0.003mol / l, Zn 2+ The concentration is 0.03mol / l. Another 0.75 mol of hexamethylenetetramine was prepared and loaded into a basic burette, and fixed ...

Abstract

The invention provides a CBD production method of Mg-doped ZnO nanorods. The method comprises the following steps: dissolving zinc acetate and magnesium acetate in deionized water to prepare a zinc acetate solution, dropwise adding hexamethylenetetramine to the zinc acetate solution under a magnetic hot stirring condition, obliquely placing a cleaned glass substrate in the stirred solution after whole titration is completed, and growing a one-dimensional ZnMgO nanomaterial in the closed solution. The solution is prepared from zinc acetate, magnesium acetate and hexamethylenetetramine, a titration reaction of the hexamethylenetetramine is carried out, and the ternary alloy compound ZnMgO nanomaterial is formed through a chemical bath deposition technology. Addition of a proper amount of Mg makes the forbidden band width of ZnO be wider than that of a bulk material, and the nanostructure of the ZnO is successfully doped with Mg.

Description

technical field [0001] The invention relates to a method for preparing Mg-doped ZnO nanorods by chemical bath deposition (abbreviated as CBD in English). Background technique [0002] The current nano-ZnO preparation technology mainly includes physical methods including ion evaporation, electron beam evaporation, sputtering and laser beam methods, etc., and chemical methods mainly include gas phase reaction method, template method and hydrothermal method. Among them, the hydrothermal method can control the particle growth process by controlling the experimental conditions, such as changing the reactant or the content of the reactant, the reaction temperature and the reaction time. [0003] Most of the existing synthesis methods of ZnO and MgO are costly and complicated, and the preparation process often requires expensive instruments and equipment, and the requirements for test conditions are relatively high. Contents of the invention [0004] The object of the present in...
