Progress achieved in the research on electro-reforming of methane/CO2 to produce syngas at the Fujian Institute of Physics and Materials Science. Author/Source: Date: 2018-04-02. Clicks: 87. Natural gas and CO2 can be converted into syngas through reforming reactions, which can then be further transformed into various important chemicals via Fischer-Tropsch reactions. This approach not only enables efficient utilization of natural gas but also helps to reduce greenhouse gas emissions. However, the carbon monoxide disproportionation reaction and methane thermal cracking in traditional reforming reactions tend to cause carbon deposition, and the sintering/agglomeration of catalysts at high temperatures also leads to a decline in the performance of dry reforming. Recently, the research group led by Xie Kui from the Key Laboratory of Functional Nanoscale Structure Design and Assembly at the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, combined two gas-phase electrochemical conversion processes—carbon dioxide electrolysis (CO2 + 2e- = CO + O2-) and methane oxidation (CH4 + O2- = CO + 2H2 + 2e-)—using a solid oxide electrolyte cell, thereby achieving the electrocatalytic conversion of methane/carbon dioxide into syngas and elucidating the reforming mechanism of CH4/CO2. By in-situ regulating the structure and composition of the metal/oxide interface at the Wiener scale of the ceramic electrode, this study achieved the anti-coking performance and high-temperature stability of the composite system in CH4/CO2 atmospheres; the atomic efficiency and current efficiency of electrochemical reformation of CH4/CO2 to produce syngas reached 100%. The relevant research findings were published in Science Advances. This research was funded by the **Major Research Program (Catalytic Science for Carbon-Based Energy Conversion and Utilization), the Fujian Province Entrepreneurship and Innovation Talent ‘Hundred Talents Plan’, and other sources.
