Electroreduction of carbon dioxide into higher-energy liquid fuels and chemicals is a promising but challenging renewable energy conversion technology. Among the electrocatalysts screened for carbon dioxide reduction, nanometer nitrogen-doped graphene quantum dots (NGQDs) is identified to be electrocatalysts that trigger CO2 electroreduction into high-energy liquid fuels — creating ethylene and ethanol.
NGQDs exhibit high activity towards the electrochemical reduction of CO2 and, more importantly, they preferentially produce multi-carbon hydrocarbons and oxygenates, especially the C2 products ethylene (C2H4) and ethanol (C2H5OH) at high excellent efficiencies.
Carbon is typically not a catalyst and graphene is largely made up of carbon. Adding nitrogen atoms into the graphene dots can trigger chemical reactions as a response to electric current and carbon dioxide.
