Wang, Cheng deKrafft, Kathryn E. Lin, Wenbin Pt Nanoparticles@Photoactive Metal–Organic Frameworks: Efficient Hydrogen Evolution via Synergistic Photoexcitation and Electron Injection Pt nanoparticles of 2–3 nm and 5–6 nm in diameter were loaded into stable, porous, and phosphorescent metal–organic frameworks (MOFs <b>1</b> and <b>2</b>) built from [Ir­(ppy)<sub>2</sub>(bpy)]<sup>+</sup>-derived dicarboxylate ligands (<b>L</b><sub><b>1</b></sub> and <b>L</b><sub><b>2</b></sub>) and Zr<sub>6</sub>(μ<sub>3</sub>-O)<sub>4</sub>(μ<sub>3</sub>-OH)<sub>4</sub>(carboxylate)<sub>12</sub> secondary building units, via MOF-mediated photoreduction of K<sub>2</sub>PtCl<sub>4</sub>. The resulting Pt@MOF assemblies serve as effective photocatalysts for hydrogen evolution by synergistic photoexcitation of the MOF frameworks and electron injection into the Pt nanoparticles. Pt@<b>2</b> gave a turnover number of 7000, approximately five times the value afforded by the homogeneous control, and could be readily recycled and reused. building units;hydrogen evolution;Electron InjectionPt nanoparticles;MOFs 1;Efficient Hydrogen Evolution;nm;Synergistic Photoexcitation;K 2PtCl;turnover number;MOF frameworks;Pt nanoparticles;electron injection;L 1 2012-05-02
