Multiphase nanocomposite material production

Abstract

A rhombohedral Zn2SiO4/cubic ZnFe2O4/hexagonal SiO2/C nanocomposite material includes a rhombohedral zinc orthosilicate (Zn2SiO4) phase, a cubic zinc ferrite (ZnFe2O4) phase, and a hexagonal silicon dioxide (SiO2) phase. The rhombohedral Zn2SiO4/cubic ZnFe2O4/hexagonal SiO2/C nanocomposite material exhibits a morphology including spherical microscale particles with an average diameter ranging from 0.8 micrometer (μm) to 1.8 μm and irregular nanoscale aggregates with an average diameter ranging from 50 nanometer (nm) to 110 nm. The rhombohedral Zn2SiO4/cubic ZnFe2O4/hexagonal SiO2/C nanocomposite material has an adsorption capacity for basic fuchsin dye of greater than or equal to 140 milligrams per gram (mg/g). Furthermore, a method for producing the rhombohedral Zn2SiO4/cubic ZnFe2O4/hexagonal SiO2/C nanocomposite material includes calcination of metal precursors.
