“Precious, shiny metals are the focus of my research – but only in tiny quantities because I look at individual atoms. Expensive platinum, for example, which is used as a catalyst in fuel cells. With my colleagues, I look for inexpensive alternatives. We use high-resolution electron microscopy for this purpose. We could thus show that the arrangement of platinum and nickel in specially shaped nanoparticles is decisive for their performance. As a result, catalysts were designed that are ten times more efficient than pure platinum – and thus significantly cheaper.”
