Single‐Atom Catalysts: Ambient Synthesis of Single‐Atom Catalysts from Bulk Metal via Trapping of Atoms by Surface Dangling Bonds (Adv. Mater. 44/2019)

A facile dangling-bond trapping strategy to construct single-atom catalysts under ambient conditions from easily accessible bulk Fe is presented by Yuen Wu and co-workers in article number 1904496. Oxygen dangling bonds on graphene oxide act like four fingers that pinch the Fe atoms out of the Fe foam. Subsequently, the metal atoms are pulled out of the metal foam by the FeO bonds under the assistance of sonication to give Fe-single-atom/graphene oxide materials.
