1. A porous particulate nanocomposite material comprising, as determined by X-ray diffraction:
an orthorhombic CaB2O4 crystalline phase;
an orthorhombic Co3(BO3)2 crystalline phase;
an orthorhombic PbO2 crystalline phase; and,
a cubic Co3O4 crystalline phase,
wherein the porous particulate nanocomposite material is in the form of particles having a matrix phase with a smooth surface and in which sharp-edged plates are embedded and protrude, and
wherein an atomic concentration of boron in the nanocomposite material is from about 1 to about 10 atom %, an atomic concentration of lead is from about 1 to about 10 atom %, an atomic concentration of calcium is from about 5 to about 20 atom %, and an atomic concentration of cobalt is from about 5 to about 20 atom %, based on the total number of atoms in the nanocomposite material.
