Abstract

The invention belongs to the field of the preparation technology and catalysis of nanometer materials and particularly discloses an eight-foot-shaped Pt-Cu alloy nanometer material and a synthetic method of the eight-foot-shaped Pt-Cu alloy nanometer material. In the method, chloroplatinic acid and copper chloride serve as precursors, tetraethylene glycol serves as a solvent and a reducing agent,polyvinylpyrrolidone serves as a stabilizing agent, potassium iodide serves as a morphological control agent, and the eight-foot-shaped Pt-Cu alloy nanometer material is synthesized in a microwave assisting method. The synthetic method is quick and simple, high in energy efficiency and small in pollution, and the obtained eight-foot-shaped Pt-Cu alloy nanometer material is single in shape and evenin size; and the prepared eight-foot-shaped Pt-Cu alloy nanometer material has good electro-catalysis activity and can be applied to the fields such as bio-sensing, optical conduction and electrochemistry.

Description

technical field [0001] The invention belongs to the technical field of novel nanomaterials and preparation thereof, and in particular relates to an octapod-shaped Pt-Cu alloy nanomaterial and a synthesis method thereof. Background technique [0002] Materials synthesis is at the heart of developments in the field of nanoscience. Platinum group metals are industrially important catalysts, and their high catalytic performance in some important chemical synthesis is still irreplaceable. However, since platinum group metals are relatively rare in natural resources, they are expensive and costly to use. For this reason, in recent years, people try to use nanotechnology to prepare single metal and its alloy nanoparticles with different shapes and structures, so as to improve their catalytic efficiency, reduce their dosage and reduce their cost. Among them, alloy nanomaterials can not only reduce the amount of platinum group metals, but also improve their catalytic performance. ...
