| titleOfInvention | Method for preparing nano Co by using liquid cathode glow discharge plasma technology3O4Method (2) |
| abstract | The invention discloses a method for preparing nano Co by using liquid cathode glow discharge plasma technology 3 O 4 Method (2) of containing Co 2+ The solution is introduced into a liquid cathode glow discharge plasma generating device, a high-voltage direct current power supply supplies electric energy, a platinum needle electrode sealed in a quartz tube is used as an anode, and the platinum needle electrode contains Co 2+ The solution flows through a buffer bottle under the drive of a peristaltic pump, and finally overflows from the top end of a capillary tube inserted with a graphite carbon rod, and the overflowing solution is used as a discharge cathode. When 550-660V voltage and 45-90 mA current are applied between the anode and the cathode, the liquid overflowing from the top end of the capillary generates glow discharge plasma accompanied by the generation of brownish black turbid liquid, and after continuous discharge is carried out for 2-4 h, the product is collected, and the nano Co with the sheet structure is obtained 3 O 4 . The invention utilizes liquid cathode glow discharge plasma to prepare Co 3 O 4 The nano-particles have the advantages of simple process, mild conditions, controllable process, less impurities in the product, high purity, good dispersibility, less types of used chemical reagents, low dosage, no secondary pollution and the like. |
