Multicomponent nanocomposite material

Abstract

A particulate Ca2PbO4/PbO/Co3O4/C nanocomposite material comprising, as determined by X-ray diffraction (XRD): elemental carbon (C); an orthorhombic lead oxide (PbO) crystalline phase; an orthorhombic calcium lead oxide (Ca2PbO4) crystalline phase; and, a cubic cobalt oxide (Co3O4) crystalline phase. The particulate nanocomposite material is characterized by having, based on the total number of atoms in the nanocomposite material: an atomic concentration of carbon of from about 1 atomic percent (at. %) to about 10 at. %; an atomic concentration of lead (Pb) of from about 5 at. % to about 15 at. %; an atomic concentration of calcium (Ca) of from about 10 at. % to about 25 at. %; and, an atomic concentration of cobalt (Co) of from about 10 at. % to about 20 at. %.
