Abstract

A method for manufacturing strepto-shaped cobalt platinum alloy by using octreotide acetate as a template mainly comprises the steps that the octreotide acetate is dissolved through pH2-3 hydrochloric acid, the octreotide acetate is regulated into an acid solution, a cobalt chloride solution and a platinum chloride solution which are the same in amount are simultaneously added in the regulated solution with the mole ratio of 1:10-20, the solution is then put in a water bath constant temperature oscillator, and hatching is carried out for 20-26 hours under the temperature of 13-25 DEG C at 100-200 rpm.; then, the reducing agent sodium borohydride is added in the hatched solution at a time so that the hatched solution is changed into dark black from light yellow, and the strepto-shaped cobalt platinum alloy is obtained, wherein the mole ratio of the reducing agent sodium borohydride and the octreotide acetate is 1:25-35. The method for manufacturing the strepto-shaped cobalt platinum alloy by using the octreotide acetate as the template has the advantages that the manufacturing technology is simple, conditions are mild, the strepto-shaped cobalt platinum alloy is cheap and easy to obtain, the reaction is easy to control, the productivity is high, and mass production is easy to achieve.

Description

technical field [0001] The invention belongs to the technical field of nano-alloy materials, in particular to a preparation method of nano-materials. Background technique [0002] It is well known that in many cases the properties of alloying are enhanced by coordination effects. Due to its strong catalytic and magnetic properties, cobalt-platinum alloys are widely used in catalysis, sensors, electronic and magnetic devices. Therefore, the preparation of cobalt-platinum alloys with regular morphology and good dispersion has attracted great interest. [0003] There are many preparation methods for cobalt-platinum alloys, mainly including molecular beam epitaxy, magnetron sputtering, and chemical synthesis methods to prepare cobalt-platinum alloys, such as colloidal synthesis, electrochemical deposition, and polyol co-reduction. Some of the above preparation methods have high technical requirements, expensive equipment, some complicated processes, and greater environmental po...
