Scientists at the Vienna Univer-iity of Technology found a method o locate single gold atoms on a sur-ace. This should pave the way to bet- ter and cheaper catalysts. Single gold atoms are potentially the most reactive catalysts for chemical reactions. However, when gold atoms are placed on a surface they tend to ball up into tiny nuggets consisting of several atoms. A team of surface scientists now managed to fix single gold atoms on special sites of an iron-oxide surface. This could open the door to more efficient catalysts, requiring less of the precious material.
