1. A particulate nanocomposite material comprising, as determined by X-ray diffraction:
carbon;
an orthorhombic MgFe(BO3)O crystalline phase;
an orthorhombic CaB2O4 crystalline phase,
a monoclinic Mg2B205 crystalline phase; and,
wherein, based on the total number of atoms in the nanocomposite material and as determined by energy dispersive X-ray spectroscopy (EDX):
the atomic concentration of carbon (C) is from about 0.1 to about 5 atom %;
the atomic concentration of calcium (Ca) is from about 5 to about 15 atom %;
the atomic concentration of boron (B) is from about 1 to about 10 atom %;
the atomic concentration of iron (Fe) is from about 5 to about 15 atom %; and,
the atomic concentration of magnesium (Mg) is from about 5 to about 15 atom %.
