In a monumental breakthrough, scientists have achieved a remarkable feat – creating the thinnest unsupported gold ever recorded, measuring two atoms thick. This groundbreaking advancement, engineered by researchers at the University of Leeds in the U.K., heralds a new era in material science with its unprecedented thinness of only 0.47 nanometers.
At the heart of this innovation lies the two-dimensional structure of gold, where atoms are meticulously arranged in two layers, forming a surface composed solely of atoms. Published in the esteemed journal Advanced Science, this achievement showcases the unparalleled thinness of monatomic gold, surpassing previous endeavours by a considerable margin.
Lead author of the study, Sunjie Ye, underscores the transformative potential of this breakthrough. “Our work represents the first fabrication of freestanding 2D gold with a sub-nanometer thickness, unlocking a new frontier in nanotechnology,” says Ye.
Overcoming the challenge of producing ultrathin 2D metal nanomaterials without a solid substrate posed a significant obstacle. However, researchers devised a novel production technique involving chloroauric acid and a specialized “confinement agent,” enabling the formation of gold nanosheets.
This discovery’s implications span various industries, offering promising applications in medicine and electronics. Notably, the 2D gold exhibits remarkable efficiency in catalysis, potentially revolutionizing industrial processes by catalyzing chemical reactions with unprecedented effectiveness.
Stephen Evans, a Leeds researcher, highlights this breakthrough’s economic advantages. “Our findings suggest that industry could achieve comparable catalytic effects with reduced gold usage, translating into significant cost savings,” notes Evans.
Beyond catalysis, monatomic gold holds promise in diverse fields, including water purification and medical diagnostics, owing to its inherent flexibility and unique properties.
While this achievement marks a significant milestone, ongoing advancements in nanomaterial development continue to drive innovation. For instance, researchers from the Chinese Academy of Sciences have fabricated monatomic gold sheets supported by bulk crystals, showcasing the evolving landscape of nanotechnology.
Creating the world’s thinnest monatomic gold opens doors to limitless possibilities, ushering in a future defined by innovation and efficiency. Whether catalyzing reactions or enabling foldable electronics, the potential of monatomic gold knows no bounds.
