The invention discloses a method for preparing a single-wall
carbon nanohorn-hollow nanogold compound. The method for preparing the single-wall
carbon nanohorn-hollow nanogold compound comprises the steps that single-wall
carbon nanohorn powder, water and PDDA are mixed, the single-wall carbon nanohorn
powder is made to be dissolved completely through ultrasonic
waves, and then a single-wall carbon nanohorn solution is obtained; CoCl2, PVP K30 and water are mixed, the CoCl2 and the PVP K30 are made to be dissolved completely through stirring, a CoCl2 solution is obtained,
deoxidization is conducted by introducing
nitrogen into the solution, an NaBH4 solution is added dropwise under the stirring condition, CoCl2 reduction is conducted, and then a
cobalt solution is obtained; the single-wall carbon nanohorn solution is added to the
cobalt solution, an HAuCl4 solution is added after the single-wall carbon nanohorn solution and the
cobalt solution are evenly mixed,
sediment is collected in a centrifugal mode, washing is conducted, re-suspension is conducted with water, and thus the single-wall carbon nanohorn-hollow nanogold compound is obtained. According to the method for preparing the single-wall carbon nanohorn-hollow nanogold compound, in-situ synthesis of the single-wall carbon nanohorn-hollow nanogold compound is achieved according to a one-
step method, the process is simple, the time is short, the yield is high, stripping between components is avoided effectively, and the prepared compound is high in stability, resistant to shock and high in
shear resistance, has more binding sites, and is larger in specific surface area and higher in physical adsorption capacity and
chemical adsorption capacity.
