Scientists create the world's thinnest gold
  • New 2D version of gold is two layers of atoms on top of each other, and it’s 0.47 nanometers thick -- 0.000001 the thickness of a human fingernail.
  • It’s 10x more efficient as a catalytic substrate than industry-standard large gold nanoparticles, making it useful as a catalyst for a range of industrial processes.
  • Other applications include the medical device and electronics industries, and water purification systems.
  • Creating the material required reducing chloroauric acid (which contains gold) into metal, with the help of another chemical that keeps the gold two atoms thick.
  • This method opens up new routes for developing other 2D metals.
