Show moreThis thesis presents new insights into the reduction of carbon dioxide to methane and ethylene on copper electrodes. This electrochemical process has great potential for the storage of surplus renewable electrical energy in the form of hydrocarbons. The research described in this thesis focuses on the molecular reaction mechanism, to identify key intermediates that determine the product selectivity. Show less
