Understanding the cooperative interactions of metal nanoparticles with active supports is essential to controlling their catalytic activities and reaction pathways. These interfacial interactions can be achieved through two mechanisms: interfacial charge redistribution and interfacial restructuring.  In the last few years, a number of advances have been made by our research team toward tuning the metal-support interactions. The success of our approach capitalizes on nanoconfined spaces (e.g., confined interface restructuring), complex oxide supports (e.g., perovskite oxides), and 2D material edge sites (e.g., boron nitride), demonstrating that uniquely strong interfacial interactions and cooperativities between nanoparticles and supports can emerge through judicious structural choices of metals and supports. This presentation will focus on the following three synergistically linked research activities: (1) sacrificial strong metal-support interactions, (2) “intelligent” metal-support interactions, and (3) photochemically induced metal-support interactions. The interconnections among the above three metal-support interactions will be also discussed.
