Abstract

Using carbon dioxide and nickel nitrate as the carbon and nickel sources respectively, a carbon-coated NiO/Ni (NiO/Ni@C) composite was synthesized via a one-step solution combustion method. Ethanolamine was used as the CO2 adsorption solution, with nickel nitrate dissolved in it to form the combustion precursor at a molecular level. The as-obtained NiO/Ni nanoparticles exhibited spherical morphology with an average size of 30
