So far as environmental super villains go , atmospheric carbon is the kingpin of criminal offense . And just like in the comic books , each time we consider we have a way to secure it up for good .
Whatever we need is something cheap . Scalable . Something which can have a trust of ripping enough carbon from the atmosphere to will make a difference . Well , a new technique from researchers in Australia could be what we’ve been looking for .
Experts from RMIT University in Melbourne have created technology that can transfer carbon dioxide gas into particles of what is generally pure soot .
Better still, using the metal gallium as a solvent means the whole process can take place at room temperature, given the element’s remarkably low melting point.
“To date, CO2 has only been converted into a solid at extremely high temperatures, making it industrially unviable,” says RMIT physical chemist Torben Daeneke.
“By using liquid metals as a catalyst, we’ve shown it’s possible to turn the gas back into carbon at room temperature, in a process that’s efficient and scalable.”
