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. ...
