"exsolution process activated by microwave (a few seconds exposure at moderate temperature of 400ºC and without reducing atmospheres so no need for hydogen): metal atoms migrate and anchor to surface, producing strong and sable nickel nanocatalysts improving catalytic efficiency... active and stable reaction of CO production from CO2... storing and converting renewable energy, biogas reforming reactions, CO2 hydrogenation reactions, functionalizing electrodes for fuel cells and/or high-temperature electrolyzers"
