Heterostructure nanowires with intermetallic or alloy core and carbon nanotube shell, and manufacturing method thereof

摘要

PURPOSE: A hetero-nanowire consisting of intermetallic compound or alloy core and carbon nanotube shell and a synthesizing method are provided to include inter metallic compound or alloy inside the wire by uniformly mixing metal oxides and controlling compound condition. CONSTITUTION: A synthesizing method of a hetero-nanowire consisting of intermetallic compound or alloy core comprises the following steps: putting metal oxide compound into a reactor; eliminating remnant oxygen within the reactor by lowering degree of vacuum; injecting carrier gas under a vacuum atmosphere; increasing internal temperature of the reactor to a reaction temperature; injecting hydrocarbon gas into the reactor; and reacting the hydrocarbon gas with the metal oxide compound. 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.
