This work was completed in collaboration with associate researcher Ma Ming and professor Jong Hyeok Park of Yonsei University in South Korea. Ma Ming is the first author and co-corresponding author. Methane gas has attracted much attention as a fuel with low carbon dioxide release, but due to its greenhouse effect thirty times that of carbon dioxide, leakage during its mining and transportation process will cause a series of environmental problems and climate change. Therefore, the conversion of methane into liquid fuel for storage and transportation can better solve the above problems. At present, scientists have conducted a lot of research on the oxidative conversion of methane, but the conditions required for various conversion methods are relatively difficult, such as the need for high temperature and high pressure reactions, and the use of precious metal catalysts. The electrochemical catalytic conversion process can be carried out at room temperature, and has the potential for long-term continuous reaction, which is conducive to industrial conversion production. Based on the above considerations, the research team successfully developed a new ZrO2: NiCo2O4 quasi-solid solution anode catalyst, and used the catalyst to achieve the methane electrocatalytic conversion to propionic acid and acetone. After 20 hours of reaction, the methane conversion efficiency reached 47.5%. In the ZrO2: NiCo2O4 catalyst, NiCo2O4 is the main catalytic component for the oxidative conversion of methane. The high catalytic activity of Ni atoms is used to realize the rapid oxidation of methane, making n-propanol and isopropanol the preliminary intermediate products. With the extension of the reaction time, n-propanol and isopropanol are further oxidized and converted into propionic acid and acetone. As the final product of the methane oxidation process, the propionic acid yield after 20 hours of reaction is calculated to be 1173umol / gcat / h. This work provides new research ideas for the research of electrocatalytic conversion of methane. This work was supported by the Shenzhen Advanced Academy Outstanding Youth Innovation Fund.
