Pt Nanoparticles@Photoactive Metal–Organic Frameworks: Efficient Hydrogen Evolution via Synergistic Photoexcitation and Electron Injection
Abstract
Pt nanoparticles of 2-3 nm and 5-6 nm in diameter were loaded into stable, porous, and phosphorescent metal-organic frameworks (MOFs 1 and 2) built from [Ir(ppy)(2)(bpy)](+)-derived dicarboxylate ligands (L(1) and L(2)) and Zr(6)(μ(3)-O)(4)(μ(3)-OH)(4)(carboxylate)(12) secondary building units, via MOF-mediated photoreduction of K(2)PtCl(4). 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@2 gave a turnover number of 7000, approximately five times the value afforded by the homogeneous control, and could be readily recycled and reused.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
