What are Single-Atom Catalysts and Why are They Important?
Single-atom catalysts (SACs) represent a groundbreaking development in catalysis. In SACs, individual metal atoms are dispersed on a support material, maximizing the utilization of precious metals and enhancing catalytic performance. These catalysts exhibit unique properties due to the isolated nature of the metal atoms, which can lead to exceptional activity and selectivity. Techniques like Scanning Tunneling Microscopy (STM) and Aberration-Corrected TEM are essential for characterizing these single-atom sites and understanding their behavior.
