Scientists have come up with a new way to capture CO2: an artificial leaf that mimics real leaves.

Plants are among the most effective agents of carbon sequestration, a process whereby carbon dioxide is locked up from the atmosphere. During photosynthesis plants convert CO2 and water into oxygen and glucose thanks to the pigment chlorophyll in their leaves. They can do this by help of sunlight, which chlorophyll absorbs in order to facilitate chemical reactions within plant cells.

In order for more CO2 to be sequestered then, we can plant more plants. We can also boost plants’ ability to absorb CO2 from the air, such as by allowing them to grow bigger roots[1] or by tweaking their efficiency[2] at carbon capture.

A team of scientists from the University of Waterloo in Canada, California State University in the United States and the City University of Hong Kong has come up with another way we can capture CO2 from the atmosphere: by creating an artificial leaf that m...
