One-dimensional metal doped rutile titanium dioxide nanowire and preparation method thereof

The invention discloses a preparation method of a one-dimensional metal doped rutile titanium dioxide nanowire. The preparation method comprises the following steps: (1) preparing mixture powder of atitanium source, sodium chloride, disodium hydrogen phosphate and metal salt in a certain proportion; (2) putting the powder into a heating furnace with a certain atmosphere, and carrying out high-temperature melting growth reaction for a period of time; and (3) transferring the sintered product into boiling water, cleaning, centrifuging, removing impurities, and carrying out vacuum drying to obtain the one-dimensional metal doped rutile TiO2 nanowire. The one-dimensional metal doped rutile TiO2 nanowire is prepared by adopting a molten salt method, the reaction condition is simple, and the product uniformity is good. The invention also provides an application of the one-dimensional metal doped rutile titanium dioxide nanowire, and the one-dimensional metal doped rutile titanium dioxide nanowire shows an excellent
