[ASAP] In-Plane Electronic Metal–Support Interaction Enables Efficient Sulfur Catalysis on Ni Single-Atom Catalysts

AI Insight

This study investigates Ni single-atom catalysts (SACs) and demonstrates that in-plane electronic metal–support interactions (EMSI) play a critical role in enabling efficient sulfur catalysis. By anchoring individual Ni atoms within a support material, the researchers show that electronic charge transfer between the metal atom and its surrounding support modifies the catalytic properties of Ni, optimizing its activity toward sulfur-related reactions. The in-plane geometry of this interaction appears to be a key structural feature distinguishing this mechanism from conventional metal–support interactions observed in nanoparticle-based catalysts.

Why it matters

Sulfur catalysis is relevant to energy storage technologies, particularly lithium–sulfur batteries, where sluggish reaction kinetics remain a major bottleneck; understanding and tuning metal–support interactions at the single-atom level could guide the rational design of more efficient and cost-effective catalysts using minimal amounts of precious or earth-abundant metals.
