Natural gas and carbon dioxide are converted into synthesis gas through reforming reactions. The further funding of the reaction further converts them into various important chemicals, which can not only achieve the purpose of efficient natural gas utilization, but also effectively reduce greenhouse gas emissions. However, in the conventional reforming reaction, Carbon monoxide disproportionation reaction and methane pyrolysis easily produce carbon deposition, and the problem of catalyst sintering/agglomeration at high temperatures can also lead to attenuation of dry reforming performance.
Recently, the Xie Kui Group of Key Laboratory of Functional Nanostructure Design and Assembling, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, electrolysis of CO2 through a solid oxide electrolytic cell (CO 2+2e-=CO+O 2-) and methane oxidation (CH 4+O2-=CO+2H2+2e-) combines two gas-phase electrochemical conversion processes to achieve the electrocatalytic synthesis of methane/carbon dioxide to syngas and clarify the CH 4/CO 2The mechanism of reforming. This study obtained a composite system for CH by in-situ modulating the Wiener scale metal/oxide interface structure and components of the ceramic electrode. 4/CO 2Atmospheric resistance to carbon deposition and high temperature stability, electrochemical reforming CH 4/CO 2Synthesis gas has atomic and current efficiency up to 100%.
The related research results were published in the Science Advances. The research was funded by the National Fund's major research program (Catalytic Science for Carbon-Based Energy Conversion and Utilization), and the “100-Year Plan” for entrepreneurial and innovative talents in Fujian Province.
