A method for producing metal nanofoams

The invention relates to a method for producing metal nano foams. In this case, at least at least one metal salt (MS), citric acid (ZS) and water (W) as well as starch can be used (S) as starting materials, which are mixed to form a rheopexic, non-Newtonian fluid, rheopexic the resulting non-Newtonian fluid is at least provided with an exothermic reaction within an inert environment to a block of metal nano-foam.
