Abstract
A porous particulate nanocomposite material includes, 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. 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.
