The method of preparing porous metal by using mixed gas solves the problem that the existing micro-nano porous metal preparation process mainly focuses on the initial formation process of metal materials, the method is complicated, heavily relies on templates, and has high requirements for production equipment. The method for preparing the porous metal material: 1. The metal material is first cleaned with acetone, and then cleaned with absolute ethanol and deionized water in sequence; 2. The cleaned metal is heated to 550-850 ° C under the protection of an inert gas, and then The mixed gas composed of fuel gas and oxidizing gas is passed into the carrier body for porous treatment. The invention directly utilizes fuel gas and oxidizing gas to form the expansion and overflow of H2O and CO2 gas inside the metal, and forms a porous structure on the surface and inside of the metal, which has the advantages of simple process, convenient preparation and no pollution, and can be prepared in the Secondary processing can be realized on complex metal material devices, and the requirements for equipment are low.
