摘要：NOVELTY - Preparing noble metal gold particle catalytically-grown tin oxide nanowire, comprises ultrasonically dissolving tin salt and noble metal precursor in absolute ethyl alcohol solvent to prepare a precursor solution, injecting the precursor solution into a combustion reactor with a mixed gas of hydrogen and air as pilot flame at the feeding speed of 4-8 ml/minute via an injection pump and an atomizer to carry out combustion-pyrolytic reaction, using filter paper to collect the tin oxide nanowire final product in reaction chamber, where tin oxide nanowire edge contains noble metal gold particles. USE - The tin oxide nanowire is useful in dye-sensitized solar cells and gas sensitive sensors. ADVANTAGE - The tin oxide nanowire is provided with the noble metal gold particles at its sharp end, which can generate interface plasma resonance effect with tin oxide as a semiconductor. DETAILED DESCRIPTION - Preparing noble metal gold particle catalytically-grown tin oxide nanowire, comprises ultrasonically dissolving tin salt and noble metal precursor in absolute ethyl alcohol solvent to prepare a precursor solution, injecting the precursor solution into a combustion reactor with a mixed gas of hydrogen and air as pilot flame at the feeding speed of 4-8 ml/minute via an injection pump and an atomizer to carry out combustion-pyrolytic reaction, using filter paper to collect the tin oxide nanowire final product in the reaction chamber, where the tin oxide nanowire edge contains noble metal gold particles, the tin salt is tin tetrachloride pentahydrate, the noble metal precursor is chloroauric acid, the total molar concentration of tin salt and the noble metal precursor is 0.1-0.2 mol/l and the molar ratio of tin and gold is 50:1-250:1.
