Direct synthesis of methane from CO_2-H_2O co-electrolysis in tubular solid oxide electrolysis cells

摘要

Directly converting CO_2 to hydrocarbons offers a potential route for carbon-neutral energy technologies. Here we report a novel design, integrating the high-temperature CO_2-H_2O co-electrolysis and low-temperature Fischer-Tropsch synthesis in a single tubular unit, for the direct synthesis of methane from CO_2 with a substantial yield of 11.84%.
