Researchers have isolated a new supermaterial called 'goldene,' a freestanding, atom-thick sheet of gold with unique electronic and surface properties, created by etching away layers from a layered crystal, opening new possibilities in catalysis, electronics, and medicine.
Scientists have successfully created "goldene," an ultra-thin version of gold that exhibits semiconductor properties when just one atom layer thick. This breakthrough material, similar to graphene, could have wide-ranging applications in carbon dioxide conversion, water purification, communications technologies, and more. The discovery was made using a century-old technique inspired by Japanese craftspeople and could potentially lead to the development of similar materials using other metals.
Researchers at Linköping University have successfully created a single-atom layer of gold, termed goldene, using a method inspired by Japanese forging art. This breakthrough has given gold new properties, making it suitable for various applications such as carbon dioxide conversion, hydrogen production, and value-added chemical production. The material, titanium gold carbide, was created by intercalation and then exfoliated using a modified version of Murakami's reagent. The resulting goldene sheets have two free bonds when two-dimensional, opening up possibilities for a wide range of applications. The researchers are now exploring the potential for other noble metals and additional future applications.
