Method for preparing La2CuO4 perovskite/foamed nickel electrode by adopting spark plasma sintering technology

The invention discloses a method for preparing a La2CuO4 perovskite/foamed nickel electrode by adopting a spark plasma sintering technology, and relates to the technical field of material preparation. The method for preparing the La2CuO4 perovskite/foamed nickel electrode by adopting the spark plasma sintering technology comprises the following steps: pretreating foamed nickel, preparing La2CuO4 perovskite precursor powder by adopting a sol-gel method and preparing a composite electrode. The preparation method of the composite electrode comprises the following steps: uniformly coating La2CuO4 perovskite precursor powder on the surface of foamed nickel, and carrying out vacuum plasma sintering. The foam material composite electrode is prepared by generating the perovskite catalyst on the surface of the foam nickel in situ through the La2CuO4 perovskite powder precursor, the use of an adhesive is avoided through the high-temperature vacuum effect of the vacuum plasma sintering furnace, the prepared electrode is
