Optimization of electrochemical reduction of high-pressure CO2 to hydrocarbon (methane) at nickel electrode in cold methanol
Electrochemical reduction of CO2 in conventional aqueous electrolytes is often limited by low CO2 solubility and the competing hydrogen evolution reaction (HER). To address these challenges, we investigated CO2 electroreduction on a Ni electrode in a nonaqueous methanol/LiCl electrolyte under high CO2 pressure (1.0 MPa...
