NChem Research Highlights: Catalysis, catenanes and qubits

Let’s dive straight in: Catalysts’ performances can be tuned by including other metals – for example, a CuPt alloy. You might expect that, for an effective catalyst, the surface would feature more of the reactive metal – in this case, Pt. But no! The less reactive Cu atoms migrate to the surface, where they create islands of Pt atoms to do the biz with the CO molecules.
