説明
<jats:title>Abstract</jats:title><jats:p>Atomically precise silver (Ag) nanoclusters are promising materials as catalysts, photocatalysts, and sensors because of their unique structures and mixed‐valence states (Ag<jats:sup>+</jats:sup>/Ag<jats:sup>0</jats:sup>). However, their low stability hinders the in‐depth study of their intrinsic reactivity and catalytic property accompanying their redox processes. Herein, we demonstrate that a molecular hybrid of an atomically precise {Ag<jats:sub>27</jats:sub>}<jats:sup>17+</jats:sup> nanocluster and polyoxometalates (POMs) can efficiently cleave H<jats:sub>2</jats:sub> into protons and electrons. The Ag nanocluster accommodates electrons through the redox reaction from {Ag<jats:sub>27</jats:sub>}<jats:sup>17+</jats:sup> to {Ag<jats:sub>27</jats:sub>}<jats:sup>13+</jats:sup>, and the POM ligands play the following important roles: (i) a significant stabilization of the typically unstable Ag nanocluster to preserve its structure during the redox reaction with H<jats:sub>2</jats:sub>, (ii) formation of a unique interface between the Ag nanocluster and metal oxides for efficient H<jats:sub>2</jats:sub> cleavage, and (iii) storage of the generated protons on the negatively charged basic surface.</jats:p>
