| description | The invention provides a method for preparing nano nickel hydroxide through an electrolytic method, and belongs to the technical field of nano material preparation. A high-voltage direct-current powersupply is used for providing electric energy, a homemade platinum needle sealed in a quartz tube is used as an anode, and a nickel nitrate solution overflowing from the upper end of a capillary tubeis used as a cathode. In the electrolysis process, nickel ions in the solution are continuously consumed, and light green precipitates are generated at the bottom of a collector; and after the electrolysis is finished, turbid liquid in the collector is ultrasonically dispersed, then high-speed centrifugal separation is carried out, washing is carried out with distilled water for multiple times toremove redundant nickel nitrate, vacuum drying is carried out to constant weight, and grinding is carried out to obtain light green nano Ni(OH)2. The preparation method has the advantages of mild conditions, easiness in operati |
