AXIAL HETEROSTRUCTURE NANOWIRES OF METAL OXIDES, AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A metallic oxide hetero-nanowire which is constructed in a longitudinal direction and a synthesizing method thereof are provided to synthesize in large amount through simple core-shell heterogeneous nanowire synthesis and oxidation processes. CONSTITUTION: A synthesizing method of a metallic oxide hetero-nanowire which is constructed in a longitudinal direction comprises the following steps: putting metal oxide compound into a reactor; eliminating remnant oxygen within the reactor by lowering degree of vacuum; increasing inner temperature of the reactor while injecting carrier gas into the reactor; injecting hydrocarbon gas into the reactor; reacting the hydrocarbon gas with the metal oxide compound; synthesizing heterogeneous nanowire consists of intermetallic compound or alloy core; cooling the reactor to room temperature; and oxidizing the heterogeneous nanowire under oxidizing atmosphere while increasing temperature. The metal oxide compound is a mixture of tin oxide and indium oxide. A mixing ratio of the tin oxide to the indium oxide is 6:1-1:6 in weight ratio. The reaction with the metal oxide compound with the hydrocarbon gas is processed at 550-850 deg Celsius and lasts within 2 hours.
