Claim:
1. A method for fabricating a one-dimensional titanium nanostructure, comprising steps: placing a heat-resistant substrate and a titanium metal in a CVD (Chemical Vapor Deposition) reaction chamber; and using a carrier gas to transport titanium tetrachloride into said CVD reaction chamber, undertaking a reaction of said titanium metal and said titanium tetrachloride to generate titanium subchloride, and letting said titanium subchloride thermolyze to form a one-dimensional titanium nanostructure on said heat-resistant substrate, under a reaction condition of a reaction temperature of 500-900° C., a deposition temperature of 500-850° C., a flow rate of a carrier gas of 0.1-10 sccm and a reaction time of 8-30 hours, wherein said heat-resistant substrate is made of graphite, and said carrier gas is nitrogen, and wherein said one-dimensional titanium nanostructure is a titanium nanowire having a diameter of 20-50 nm and a length of 2-50 μm, and wherein said titanium nanowire is a monocrystalline titanium nanowire or a polycrystalline titanium nanowire.
