1. one-dimensional rod-like CuFeS2The preparation method of compound, it is characterised in that comprise the following steps that:

  • The inorganic salts of the inorganic salts of watersoluble divalent copper and watersoluble divalent iron are dissolved in deionized water, sulphur powder is added, stirsYellow green turbid solution is mixed, the hydro-thermal reaction in water heating kettle, is then centrifuged for, and cleans, drying, up to the final product one of grey blackTie up bar-shaped CuFeS2Compound;

    Copper in molar ratio;

    iron;

    sulphur=1;

    (0.2~1);

    (0.8~1.5);

    The inorganic salts of the watersoluble divalent copper in the copper nitrate containing the crystallization water, copper chloride, copper carbonate, copper sulphate oneKind;

    The molar concentration of the inorganic salts of the watersoluble divalent copper in the solution is 0.1~1mol/L;

    The inorganic salts of the watersoluble divalent iron are selected from the ferrous nitrate containing the crystallization water, ferrous sulfate, frerrous chloride, ferrous sulfateOne kind in ammonium, ferrous carbonate;

    The molar concentration of the inorganic salts of the watersoluble divalent iron in the solution is 0.2~2mol/L;

    The sulphur powder uses inorganic sulphide powder;

    The inorganic sulphide powder is selected from the sulfuric acid sodium powder containing the crystallization water, thiosulfuric acidOne kind in sodium powder, distillation sulphur powder;

    The molar concentration of the sodium thiosulfate in the solution is 0.2~2mol/L;

    The sulphur powderAddition be 2~4g/L;

    The liner material of the water heating kettle uses the polytetrafluoroethylene (PTFE) macromolecule material of high temperature resistant to 250 DEG CMaterial;

    The temperature of the hydro-thermal reaction is 160~230 DEG C, and the time of hydro-thermal reaction is 12~36h;

    The hydro-thermal reaction is usedSolvent be water-soluble solvent.
