METHOD OF MANUFACTURING NANO-COMPOSITES INCLUDING MG0.4AL2.4O4 NANO-DONUT WITH SPINEL STRUCTURE AND MAGNESIUM OXIDE NANOWIRE

摘要

Provided are a method for manufacturing nano-composites including Mg_0.4Al_2.404 nano-donuts having a spinel structure and magnesium oxide nanowires. The method for manufacturing nano-composites comprises the steps of: preparing a substrate on which metal catalysts are deposited; heating, under the atmosphere of mixed gas of inert gas and oxygen gas, mixed powder including magnesium powder and aluminum powder to supply to the substrate; applying heat treatment to the substrate to generate magnesium oxide nanowires on the substrate; and cooling the heat-treated substrate for the substrate to enclose the outer peripheral surface of the oxide magnesium, and generating Mg_0.4Al_2.4O_4 nano-donuts having a spinel structure which are placed separately from one another, thereby providing novel nano-composites containing Mg_0.4Al_2.4O_4 nano-donuts having a spinel structure with new properties and magnesium oxide nanowires.
