High Efficiency Electrochemical Reduction of Carbon Dioxide under High Pressure on a Gas Diffusion Electrode Containing Pt Catalysts
Source abstract
Abstract
Effects of current density, pressure, and charge passed on the electrochemical reduction of gas phase under high pressure (< 50 atm) on a gas diffusion electrode containing Pt electrocatalysts were investigated. The faradaic efficiency for reduction reached 46% at a current density of . Methane was produced at a faradaic efficiency of 35%. A partial current density of was achieved for methane formation. Ethanol was also produced at a faradaic efficiency of 2.2% (partial current density of ). The faradaic efficiency for methane formation increased with increasing pressure, whereas that for hydrogen formation decreased.
