1. A method comprising:
mixing copper oxide powder and nickel oxide powder to obtain a slurry solution;
freeze casting the slurry solution of copper oxide powder and nickel oxide powder;
reducing or sintering, or both, the freeze-casted slurry of copper oxide and nickel oxide powder at a temperature of about 800 degrees Celsius to about 1000 degrees Celsius; and
after the reducing or sintering, producing a three dimensionally connected copper-nickel alloy foam of Cu9Ni1, Cu7Ni3, Cu5Ni5, Cu3Ni7, or Cu1Ni9,
wherein the nickel oxide powder has an average size of about 10 nanometers to less than about 20 nanometers, and the copper oxide powder has an average size of about 40 nanometers to about 80 nanometers,
the copper oxide powder and nickel oxide powder are mixed in water or other liquid solvent with polyvinyl alcohol and sodium polyacrylate powder.
