Combining Air Capture and Water Splitting for Generating Carbon Dioxide and Hydrogen for Synthetic Fuel Production
Background The conversion of solar energy to fuels requires both water (H2O) and carbon dioxide (CO2) as feedstocks. These feedstocks provide the carbon and hydrogen atoms necessary to form hydrocarbons. By removing oxygen from one or both of these compounds, liquid hydrocarbon fuels can be produced. Water can be converted into hydrogen and oxygen...
