Powered by Sunlight, ‘Artificial Leaf’ Successfully Produces Clean Gas From CO2 and Water (4 minute read)
Syngas is a gas usually created from fossil fuels that is used to produce a range of commodities, such as fuels, pharmaceuticals, plastics, and fertilizers. Researchers at the University of Cambridge have created an artificial leaf that is able to produce syngas in a sustainable and simple way. The leaf works by using a combination of two light absorbers and a cobalt-based catalyst. It is able to work in low light, even when it is rainy or overcast. The technology may be able to eventually produce a sustainable liquid fuel alternative to petrol.
