Artificial photosynthesis harnesses forgotten half of sunlight’s energy

A semiconductor has been created that can make use of infrared light to power an artificial photosynthesis reaction. The photocatalyst can split carbon dioxide into carbon monoxide and oxygen in what could be a new way to make the most of all of the sun’s energy. Technologies that mimic plants by harnessing solar energy to convert carbon dioxide and water into hydrocarbons and oxygen are highly sought after due to their potential for sustainable chemical production.
