1. A porous particulate nanocomposite material comprising, as determined by X-ray diffraction:
elemental carbon;
elemental nickel in a cubic crystalline phase;
a cubic NiO crystalline phase;
an orthorhombic CaB2O4 crystalline phase; and,
a MgB2O4 crystalline phase,
wherein, based on the total number of atoms in the nanocomposite material:
the atomic concentration of carbon (C) is from about 1 to about 10 atom %;
the atomic concentration of nickel (Ni) is from about 1 to about 10 atom %;
the atomic concentration of boron (B) is from about 1 to about 10 atom %;
the atomic concentration of magnesium (Mg) is from about 5 to about 15 atom %; and,
the atomic concentration of calcium (Ca) is from about 1 to about 10 atom %.
