Methane synthesis from CO2 and H2O with electricity using H-permeable membrane electrochemical cells with Ru catalyst and phosphate electrolyte

Direct electrochemical conversion of CO2 and H2O to CH4 in a combined Ru-catalyst and H2O electrolyzer system was examined at 270 °C, thus obtaining a current efficiency of 93% for CH4 formation.

High-voltage and intrinsically safe supercapacitors based on a trimethyl phosphate electrolyte

The trimethyl phosphate-based electrolyte system can be considered as a promising candidate for high-voltage and intrinsically safe supercapacitors.
