Description

technical field

[0001] The invention belongs to the field of nanometer material science, in particular to a platinum-non-precious metal alloy nanowire and its aqueous phase synthesis method and application. Background technique

[0002] Platinum has excellent catalytic properties, which are derived from its unique surface electronic structure and physical and chemical properties. It is widely used in many catalytic fields, such as hydrogenation catalysis, dehydrogenation catalysis, oxidation catalysis, cracking catalysis, etc. However, the reserves of platinum in the earth's crust are scarce, and it is difficult to mine and smelt it. Therefore, platinum must be fully and efficiently used. How to efficiently utilize noble metal platinum, improve the catalytic activity and stability of noble metal platinum catalysts, and reduce the cost of noble metal platinum catalysts is of great significance to the effective utilization of rare metals and the development of the national eco...
