Problems solved by technology

For example, the process of preparing nanowires by the template method is complicated, the preparation cycle is long, the diameter of the prepared nanowires is thick, the long diameter is small, and the yield cannot be guaranteed.
Therefore, there are still some difficult problems and challenges in the preparation of high-quality nanowires.

Abstract

The invention relates to a preparation method of a Pt-Cu linear nano-catalyst. The method comprises the following steps of adding acetyl acetone platinum and potassium iodide into oleylamine, then adding copper acetylacetonate, reacting for 3 to 24 hours at the temperature of 160 to 180 DEG C; finally washing through absolute ethyl alcohol to obtain the Pt-Cu linear nano-catalyst. The method for preparing the Pt-Cu linear nano-catalyst, provided by the invention, is simple and convenient without using a template, simple to operate, and easy for production.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and more specifically relates to a preparation method of a Pt-Cu linear nano-catalyst. Background technique [0002] One-dimensional nanomaterials refer to nanomaterials that have two dimensions in the nanoscale range in space, such as nanowires, nanorods, nanobelts, and nanotubes. Compared with nano-bulk materials, one-dimensional nanomaterials have excellent size effects and can form more complex nanoscale structures, especially one-dimensional noble metal materials well integrate the unique properties of one-dimensional nanomaterials and metals themselves, and have Different from the special physical and chemical properties of the corresponding bulk materials, it can be applied in the fields of ultra-large-scale integrated circuits, optical fibers, chemical sensors, chemical catalysis, and biomedicine. Therefore, one-dimensional noble metal nanomaterials have become the frontier ...
