| titleOfInvention | Manufacturing method of metal oxide powder |
| abstract | The present invention relates to a method for producing a polymer electrolyte membrane, comprising the steps of: adding deionized water and an electrolyte to a reactor and stirring to form an electrolyte aqueous solution; immersing a first base material made of a metal or metal alloy material to be reacted in the electrolyte aqueous solution, Connecting a second base material made of a metal or a metal alloy material having a smaller oxidation-reduction potential to the first base material and higher in corrosion resistance than the first base material to the negative electrode of the power supply; The method comprising: setting a voltage difference between substrates and operating the power supply to cause an oxidation reaction to start in the first substrate; forming an arc plasma on the surface of the first substrate, A metal oxide is formed on the surface of the first base material and is separated from the surface of the first base material, A step of selectively precipitating a precipitate that is sitting in the aqueous electrolyte solution, and a step of heat treating the precipitate selectively separated in an oxidizing atmosphere to obtain a metal oxide powder . According to the present invention, since no strong acid is used and a small amount of electrolyte and deionized water are used, there is little harmful substances or wastewater that can be generated during the process, and it is eco-friendly and cost-saving and mass production in a short time is possible . |
