Recently, Wang Qi's research group in the Applied Plasma Research Room of the Institute of Plasma Physics, Chinese Academy of Sciences has made progress in methanol oxidation reaction, and the relevant content has been published in Applied Surface Science.

　　The working principle of Direct Methanol Fuel Cell (DMFC) is that in the oxidation-reduction reaction process, the methanol at the anode loses electrons under the action of the catalyst, and passes through the external circuit to the cathode. At the same time, hydrogen ions (acid electrolyte) pass from the anode through the electrolyte membrane. It is transferred to the cathode, and then the oxygen in the cathode is catalytically reduced to obtain electrons to form a current loop to provide electrical energy. Among them, the catalyst is very important to the methanol oxidation reaction of the anode. In recent years, the relevant research has become more and more in-depth, mainly from the aspects of improving the utilization rate of precious metal catalysts, modifying the carrier and preparing alloy catalysts to improve the anti-poisoning ability. As a precious metal catalyst with excellent performance, platinum (Pt) has always received attention from researchers. Among them, the carrier supporting platinum nanoparticles often has a greater impact on the final catalytic performance. Graphene oxide is often used as a support for precious metals. However, if graphene oxide is used directly as a support, the electrochemical performance test cannot achieve the desired results.
