How to train your catalyst, one atom at a time
How do you keep a copper catalyst from losing its oomph? Just add a dusting of platinum, says a new study published in Nature Materials. A team of researchers, including scientists at the Department of Energy's SLAC National Accelerator Laboratory, investigated a class of metal nanoparticles used as catalysts in major industrial processes. They found that adding a trace amount of platinum to copper nanoparticles greatly reduced an effect known as "sintering," which causes these catalysts to degrade over time.
