Methane synthesis from CO<sub>2</sub> and H<sub>2</sub>O with electricity using H-permeable membrane electrochemical cells with Ru catalyst and phosphate electrolyte
Jun Kubota, Takaya Okumura
Abstract
Direct electrochemical conversion of CO<sub>2</sub> and H<sub>2</sub>O to CH<sub>4</sub> in a combined Ru-catalyst and H<sub>2</sub>O electrolyzer system was examined at 270 °C, thus obtaining a current efficiency of 93% for CH<sub>4</sub> formation.
