1. A NiO/MgO/CaCO3/Ca(OH)2/C nanocomposite material, comprising:
a monoclinic NiO phase;
a cubic MgO phase;
a hexagonal CaCO3 phase; and
a hexagonal Ca(OH)2 phase,
wherein the NiO/MgO/CaCO3/Ca(OH)2/C nanocomposite material has a granular morphology comprising spherical particles having an average particle diameter in a range from 10 to 50 nm; and
wherein the NiO/MgO/CaCO3/Ca(OH)2/C nanocomposite material has an oxygen content in a range from 40 to 60 atomic % (at. %), a calcium content in a range from 5 to 25 at. %, a nickel content in a range from 8 to 18 at. %, a magnesium content in a range from 8 to 18 at. %, and a carbon content in a range from 5 to 20 at. % wherein at. % is based on the total number of atoms in the NiO/MgO/CaCO3/Ca(OH)2/C nanocomposite material.
