Scientists are celebrating the \u201cexciting\u201d discovery of a material that can store carbon dioxide faster than trees.<\/p>\n
Sulphur hexafluoride is a more potent greenhouse gas than carbon dioxide and can last thousands of years in the atmosphere.<\/p>\n
The research, published in the journal Nature Synthesis, saw a team led by scientists at Heriot-Watt University in Edinburgh create hollow, cage-like molecules with high storage capacities for greenhouse gases like carbon dioxide and sulphur hexafluoride.<\/p>\n
Dr Marc Little, who jointly led the research, said: \u201cThis is an exciting discovery because we need new porous materials to help solve society\u2019s biggest challenges.<\/p>\n
\u201cFor example, direct air capture of carbon dioxide is increasingly important because even when we stop emitting carbon dioxide, there\u2019s still going to be a huge need to capture previous emissions that are already in the environment.<\/p>\n
\u201cPlanting trees is a very effective way to absorb carbon, but it\u2019s very slow. So we need a human intervention \u2013 like human-made molecules \u2013 to capture greenhouse gases efficiently from the environment more quickly.\u201d<\/p>\n
The material can absorb carbon dioxide more quickly than planting trees (John Giles\/PA) (PA Archive)The researchers used computer simulations to accurately predict how molecules would assemble themselves into the new porous material, a method which Dr Little said could be further enhanced in future through the use of artificial intelligence (AI).<\/p>\n
He said: \u201cCombining 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.<\/p>\n
\u201cIf you\u2019re able to use AI tools to predict those quicker and more accurately then we can really accelerate the rate at which we can discover these new types of porous materials without actually having to make any of them in the lab beforehand.\u201d<\/p>\n
Dr Little described the study as an \u201cimportant step\u201d to developing other materials, and added that molecules with complex structures could also be used to remove toxic compounds known as volatile organic compounds from the air and could play an important role in medical science.<\/p>\n
He said: \u201cWe see this study as an important step towards unlocking such applications in the future.\u201d<\/p>\n
As well as scientists at Heriot-Watt, the study involved researchers from the University of Liverpool, Imperial College London, the University of Southampton, and East China University of Science and Technology.<\/p>\n","protected":false},"excerpt":{"rendered":"
