1. A method of remediating a contaminated aqueous medium, the method comprising contacting the aqueous medium with an amount of a particulate nanocomposite material comprising, as determined by X-ray diffraction:
elemental carbon;
an orthorhombic TiO2 crystalline phase;
a tetragonal TiO2 crystalline phase;
a cubic CdO crystalline phase;
a hexagonal MgTiO3 crystalline phase; and,
an orthorhombic Mg0.6 Ti2.4O5,
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 1 to about 5 atom %;
the atomic concentration of magnesium (Mg) is from about 5 to about 15 atom %;
the atomic concentration of titanium (Ti) is from about 15 to about 30 atom %; and,
the atomic concentration of cadmium (Cd) is from about 1 to about 10 atom %.
