Novel Technique for Single-Atom Catalysis Using Controlled Individual Atoms

An old saying goes “never change a running system.” However, novel techniques can be much superior to former ones. Until today, chemical reactions are majorly accelerated by catalytic materials that constitute several hundreds of atoms; however, employing single atoms can offer a new strategy for catalysis.
