(麻豆淫院) -- A materials scientist at Michigan Technological University has discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it also creates something useful. And, by the way, it releases energy.

Making carbon-based products from CO₂ is nothing new, but carbon dioxide molecules are so stable that those reactions usually take up a lot of energy. If that energy were to come from fossil fuels, over time the chemical reactions would ultimately result in more carbon dioxide entering the atmosphere鈥攄efeating the purpose of a process that could otherwise help mitigate climate change.

Professor Yun Hang Hu鈥檚 research team developed a heat-releasing reaction between carbon dioxide and Li₃N that forms two chemicals: amorphous carbon nitride (C₃N₄), a semiconductor; and lithium cyanamide (Li₂CN₂), a precursor to fertilizers.

鈥淭he reaction converts CO₂ to a solid material,鈥� said Hu. 鈥淭hat would be good even if it weren鈥檛 useful, but it is.鈥�

And how much energy does it release? Plenty. Hu鈥檚 team added carbon dioxide to less than a gram of Li₃N at 330 degrees Celsius, and the surrounding temperature jumped almost immediately to about 1,000 degrees Celsius, or 1,832 degrees Fahrenheit, about the temperature of lava exiting a volcano.

Hu鈥檚 work is funded by the National Science Foundation and detailed in the article  authored by Hu and graduate student Yan Huo and published in the Journal of 麻豆淫院ical Chemistry.
