Nanostructured two-dimensional gold monolayers offer possibilities in catalysis, electronics, and nanotechnology.
Researchers have created nearly freestanding nanostructured two-dimensional gold monolayers, an impressive feat of nanomaterial engineering that could open up new avenues in catalysis, electronics, and energy conversion.
The team grew gold monolayers on an iridium substrate and embedded boron atoms at the interface between gold and iridium. This innovative technique produced suspended monoatomic sheets of gold, which had a hexagonal structure with nanoscale triangular patterns. Incorporating boron enhanced the stability and structural integrity of the gold layers, allowing the nanostructures to form.
The ability to create stable and nearly freestanding metallic monolayers over a large area has far-reaching implications."This research opens avenues for testing theories and further exploration into the potential applications of 2D metals in the various fields, including catalysis and energy conversion," says Associate Professor Andrey Lyalin of the Faculty of Science, Hokkaido University, and the other corresponding author of the study.
