EDINBURGH, Scotland – A new discovery could help to turn the tides in the war against greenhouse gases. Scientists at Heriot-Watt University in Edinburgh have created new molecules which, thanks to their hollow and cage-like structure, can store greenhouse gases.
The new material has been hailed ‘exciting’ and could remove carbon dioxide and other polluting gases from the atmosphere faster than planting trees.
The research, published in the journal Nature Synthesis, found the new discovery can also store sulphur hexafluoride, a more potent greenhouse gas which can last in the atmosphere for thousands of years.
Dr Marc Little, who jointly led the research, said: ‘This is an exciting discovery because we need new porous materials to help solve society’s biggest challenges.
‘For example, direct air capture of carbon dioxide is increasingly important because even when we stop emitting carbon dioxide, there’s still going to be a huge need to capture previous emissions that are already in the environment.
‘Planting trees is a very effective way to absorb carbon, but it’s very slow.
‘So we need a human intervention – like human-made molecules – to capture greenhouse gases efficiently from the environment more quickly.’
Researchers used AI to predict how molecules would assemble themselves into the new material, and Dr Little says the study is an ‘important step’ to developing other materials which could remove toxic compounds from the air and potentially play an important role in medical science.
He added: ‘Combining computational studies like ours with new AI technologies could create an unprecedented supply of new materials to solve the most pressing societal challenges, and this study is an important step in this direction.
