Problems solved by technology
[0005] In the process of synthesizing mesoporous germanium materials with germanium tetrachloride as a precursor, most of them need to use soft templates or hard templates as structure-directing agents. Due to the different chemical substances selected, the different synthesis parameters, and the differences in the synthesis process, the calcination temperature ranges from From 600°C to 1000°C, the chemical and physical properties of the obtained mesoporous germanium materials vary greatly, and it is difficult to meet the requirements of synthetic substances, which greatly limits the application of such materials

The invention relates to a preparation method of a mesoporous germanium material, which belongs to the technical field of preparation and application of germanium materials. The germanium tetrachloride is used as a germanium source, the sodium potassium alloy is used as a reducing agent, and toluene is used as a solvent. Stir under magnetic force to make a reaction solution. After suction filtration, roasting, washing, and vacuum drying, a mesoporous germanium material is made. This preparation method has advanced technology, detailed and accurate data, and fast preparation speed. The product is black powder with mesoporous channels. structure, high product yield, up to 95.2%, can be used as lithium ion battery negative electrode material, is a very ideal method for preparing mesoporous germanium materials.
Description
technical field [0001] The invention relates to a method for preparing a mesoporous germanium material, which belongs to the technical field of preparation and application of germanium materials. Background technique [0002] Mesoporous germanium materials have good structural adjustability and electrochemical activity, which are unmatched by other materials. Mesoporous germanium materials have high specific surface area and large pore volume, and have been widely used in the fields of adsorption, catalysis and electricity. application. [0003] The synthesis method and process of mesoporous germanium materials will directly affect the structural characteristics and properties of the material. The selection of synthesis method and template agent is the decisive factor. The reaction temperature, reaction time and calcination temperature are also important for the pore structure of porous germanium materials. Impact. [0004] The template is the basic component of the prepar...
