The present invention has the advantages of simple method for synthesizing a carbon-coated stannum nanowire, high yield, low cost and benefit to industrial production.
Description
Technical field
The present invention relates to a kind of method of synthesizing carbon covered stannum nanowire.
Background technology
Metal nanometer line is a kind of new one-dimensional nano material of discovered in recent years.Because metal nanometer line is at normal temperatures than being easier to oxidation, the carbon coating technology can effectively prevent the oxidation of metal nanometer line, and the carbon-clad metal nano wire has a good application prospect at aspects such as electrochemical energy storage, sensor, nano-devices.Chemical vapour deposition technique (CVD) is because its output height, and is simple to operate, small investment, thereby also become a kind of popular approach of current preparation nano material.The common solid catalyst of this method by cracking organic gas such as methane on fixed bed, acetylene, ethene and third rare, finally obtains product.Also do not utilize at present the report of chemical vapour deposition technique synthesizing carbon covered stannum nanowire.
Summary of the invention
The purpose of this invention is to provide a kind of low cost, the method for the synthesizing carbon covered stannum nanowire that output is high.
The method of synthesizing carbon covered stannum nanowire of the present invention may further comprise the steps:
With tin oxide is catalyst, it is 500～1000 ℃ fixed bed gas continuous-flow reacting furnace that catalyst is put into temperature, feeds acetylene, argon gas or nitrogen, and the gas flow ratio of acetylene and argon gas or nitrogen is 1: 5～1: 20, reacted 10 minutes～60 minutes, and collected product.
Above-mentioned tin oxide catalysts can adopt precipitation method preparations: dropping ammonia to tin salt precipitates fully, is deposited in the Muffle furnace 200～300 ℃ of heating 20 minutes after the filtration, and powder, porphyrize are taken out in the cooling back.
Among the present invention, said tin salt can be selected stannous sulfate, stannous chloride or phosphoric acid stannous chloride for use.
Method provided by the invention is simple, the output height, and cost is low, helps suitability for industrialized production.The carbon covered stannum nanowire diameter that is synthesized is distributed in 20～100nm, and distribution of lengths is at 500nm～5 μ m.
