Controlled Formation of Dimers and Spatially Isolated Atoms in Bimetallic Au-Ru Catalysts via Carbon-Host Functionalization

Vera Giulimondi et al.

Summary: The introduction of foreign metal atoms in the coordination environment of single-atom catalysts has become an exciting frontier in active-site engineering. By functionalizing carbon hosts, Au-Ru dimers and isolated sites can be selectively generated. The distinct catalytic fingerprints of these materials have been revealed through hydrogen evolution reaction, which also showed that inactive Au atoms can enhance the reaction kinetics of Ru counterparts even when spatially isolated.

Metal-metal interactions in correlated single-atom catalysts

Jieqiong Shan et al.

Summary: Single-atom catalysts (SACs) are promising electrocatalysts with unique geometric structures. A recent development in this field is the emergence of correlated SACs (C-SACs), which have adjacent metal single atoms participating in metal-metal interactions. Controlling these interactions allows for regulation of atomic structure and properties, leading to modulation of electrocatalytic behavior of C-SACs. Future directions include the design and development of C-SACs to create high-performing new SAC architectures.
