제목 Tuning atomic-level catalytic interaction on heterogeneous single atom catalyst
초록 Enzymes control the specific interaction between the metal cofactor, mediating ligand and the reactants to maximize the catalytic performance. Likewise, homogeneous catalysts have been designed based on this reversible and cooperative activation process for a variety of important reactions. This interaction is not well defined in heterogeneous catalyst system and complicates the precise material design for various catalytic reactions. Here, we show how single atom catalysts can mitigate this issue. We show single atoms and the interaction with the surrounding support can control the catalytic characteristics and enables atomic-level tuning of catalytic performance as a consequence. Finally, we highlight how the cooperative interplay of atomic catalysts and adjacent environments can significantly modulate overall catalytic performance. This demonstration of atomic-level tuning represents a significant step for realizing reversible structure modulation in heterogeneous catalysts.
