Platinum Nanoparticle-Decorated Porous Porphyrin-Based Metal-Organic Framework for Photocatalytic Hydrogen Production

Herein, Pt NPs of ca . 2.5 nm incorporated inside the mesopores of porphyrin-based MOF PCN-222, denoted as Pt@PCN-222, were prepared using double-solvent method followed by visible-light reduction. The obtained mesoporous MOF composite Pt@PCN-222 can effectively adsorb visible-light to promote the water splitting for hydrogen production, which gives a H 2 yield of 253 μmol·g -1 ·h -1 .
