Two nearly identical materials have completely different chemical behavior. Research teams at the University of Vienna and TU Wien studied catalysts that use the energy of sunlight to produce ammonia. Surprisingly, when the three iron atoms that form tiny triangles in these catalysts are replaced by chromium atoms, the chemical reaction no longer takes place.
