Progress in single-atom methodology in modern catalysis

The review addresses the development of the methodology of single-atom catalysts ranging from single-site to single-atom alloy systems. The preparation and characterization of single-atom catalysts and their use in a number of key catalytic reactions, including alkyne hydrogenation, are considered. The possibility of fine tuning of the surface structure of single-atom alloy catalytic systems using the adsorbate-induced segregation is analyzed for the first time.<br> The bibliography includes 312 references.
