Atomic Lego Catalysts Synthesized by Atomic Layer Deposition

CONSPECTUS:The catalytic performance of heterogeneous catalysts in terms of activity,selectivity,and stability depends greatly on their structure,involving characteristics such as particle size,composition,and morphology.Achieving atomic-level-precise control of these structures is essential to understanding structure−activity relations and to achieving selective catalysis at high activity.However,conventional methods of catalyst synthesis including impregnation,ion exchange,and precipitation often lack precise control and produce inhomogeneous active-site structures,thus leading to poor catalytic performance in many cases.
