1. A porous particulate nanocomposite material comprising, as determined by X-ray diffraction:
a Pb2SiO4 crystalline phase;
a tetragonal Mn7O12Si crystalline phase;
a hexagonal SiO2 crystalline phase; and,
a orthorhombic SiO2 crystalline phase,
wherein, based on the total number of atoms in the nanocomposite material:
the atomic concentration of silicon (Si) is from about 20 to about 35 atom %;
the atomic concentration of manganese (Mn) is from about 5 to about 15 atom %; and,
the atomic concentration of lead (Pb) is from about 5 to about 15 atom %.
