Plants take in energy from sunlight to transform atmospheric carbon dioxide (CO2) into sugars and then other materials for growth and metabolic functions. Mimicking this photochemical reaction to efficiently convert CO2 into fuels and industrially important chemicals would support a sustainable energy future and reduce greenhouse gas emissions.
