As a model of MOF, porous coordination network-224 (PCN-224) nanoparticles with the size of 100 nm have been prepared through coordinating tetrakis (4-carboxyphenyl) porphyrin (TCPP) with Zr(IV) cations during a solvothermal process, and they are then decorated with Pt nanoclusters (∼1.5 nm) by in-situ reduction.
