Atomic-level engineering of single Ag¹⁺ site distribution on titanium-oxo cluster surfaces to boost CO₂ electroreduction.

ABSTRACT: Precise control over the distribution of active metal sites on catalyst surfaces is essential for maximizing catalytic efficiency. Addressing the limitations of traditional cluster catalysts with core-embedded catalytic sites, this work presents a strategy to position catalytic sites on the surfaces of oxide clusters. We utilize a calixarene-stabilized titanium-oxo cluster (Ti₁₂L₆) as a scaffold to anchor Ag¹⁺ in situ, forming the unique nanocluster Ti₁₂Ag_4.5 with six surface-exposed Ag¹⁺ sites. The in situ transformation from Ti₁₂L₆ into Ti₁₂Ag_4.5 clusters was traced through mass spectrometry, revealing a solvent-mediated dynamic process of disintegration and reassem
