Method for rapidly synthesizing monatomic catalyst by plasma sputtering method and application thereof

The invention discloses a method for rapidly synthesizing a monatomic catalyst by a plasma sputtering method and application thereof. A catalyst carrier and active metal are synthesized by the plasma sputtering method, and the synthesized Pt1/TiOx monatomic catalyst is excellent in catalytic performance. A glassy carbon sheet, a titanium mesh, a stainless steel sheet, carbon paper and the like are used as substrates, and a carrier target material and an active metal target material are used as raw materials; and the substrate is placed on an objective table, the carrier and the active metal arealternately sputtered and deposited on the substrate by adopting a three-target plasma sputtering instrument, and alternately depositing for a plurality of times is conducted to obtain a catalyst sample. The preparation method has the advantages of controllable active metal loading capacity, high synthesis speed, simple process, low energy consumption and the like, and the mass specific activity and the conversion effic
