Preparation method of direct alcohol fuel cell anode catalytic material

Abstract

The invention provides a preparation method of a direct alcohol fuel cell anode catalytic material and relates to catalytic material preparation methods. The method comprises the following steps of selecting a Si(100) single crystal wafer as a base body, drying the Si(100) single crystal wafer, and putting the Si(100) single crystal wafer into a vacuum chamber for depositing a film; selecting Cu<60>Zr<34>Ti<x>Ni<6-x>(x=1,2,3,4 and 5) as a target material, wherein the bottom of the target material is smooth, is in good contact with a target position and can guarantee maximum heat dissipation; selecting a magnetron sputtering coating system as a film deposition device, allowing the target material Cu<60>Zr<34>Ti<x>Ni<6-x> to be aligned with the Si base body located at the center above, vacuumizing the vacuum chamber to 3*10<-4> Pa before film deposition and then introducing high-purity argon to obtain a Cu<60>Zr<34>Ti<x>Ni<6-x> amorphous alloy film. The preparation method is used for preparing the high-electrocatalytic-property, high-stability and low-cost through magnetron sputtering deposition. Through the magnetron sputtering coating system, the precision and the working efficiency are both improved, and the preparation method provides the possibility for continuous operation of a production line.

Description

technical field

[0001] The invention relates to a catalytic material and a preparation method, in particular to a preparation method of an anode catalytic material of a direct alcohol fuel cell. Background technique

[0002] Since the 21st century, human beings have relied on energy more than ever in their lives, so energy issues are a huge challenge facing society today. With the increasing consumption of fossil fuels and decreasing reserves, energy shortages and environmental pollution have become important factors restricting the development of the global economy. Therefore, clean energy with the characteristics of high efficiency, sustainable development and low (zero) emission has become one of the research hotspots of researchers in various countries today. Researchers have made extensive explorations in finding new energy sources, and clean energy sources such as direct alcohol fuel cells, wind power and solar cells have attracted more and more research.
