Catalysts play a vital role in the energy and chemical industries. One of today’s frontiers in catalysis science is to precisely control the atomic structures of active sites. In particular, single-atom catalysts (SACs) have received intense attention for unprecedented catalytic activity and selectivity enhancements in many sceneries. Meanwhile, challenges have also been recognized in characterizing such new materials. This presentation will summarize several efforts in our group on the development of heterogeneous catalysts with atomically dispersed active sites: i) Nanoceria-supported atomic Pt catalysts (denoted as Pt1@CeO2) for non-oxidative, direct conversion of methane. ii) Chemical titration of the Active Sites in Cu-Substituted Zeolites; iii) High-entropy alloy (HEA) catalysts for chemical transformations. Through the discussion of these topics, we will highlight the great potential of combining new materials discovery and novel functionality exploration for advancing both fundamental understanding and performance improvement of heterogeneous catalysts.
