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.
