Electrochemical Reduction of CO2 to Useful Fuels on Molybdenum and Molybdenum Oxide Thin-Film Catalysts
Inspired by these studies, this contribution will explore the behavior of model thin film electrodes of Mo and Mo oxides fabricated by reactive sputter deposition10. Electrochemical reduction of CO2 is performed in 0.5 M KHCO3 using a 3 electrode configuration and the reaction products are analyzed by differential electrochemical mass spectrometry, nuclear magnetic resonance spectroscopy and ionic chromatography. The surface chemistry and crystal structure of these model electrodes is also studied before and after electrochemistry via X-ray photoelectron spectroscopy and grazing angle X-ray diffraction, respectively. To the best of our knowledge, such a detailed investigation of the catalytic properties of these materials for the electroreduction of CO2 has never been presented.
