N2 - The immobilization and uniform dispersion of Noble Metal Nanoparticles (NMNPs) show great significance in many fields (e.g. catalysis, photoelectric etc.) to enhance its performance and reusability. Covalent organic frameworks (COFs), which are born with many advantages (stability, in built functional ligands, regular channels, etc.), are potential substrates for the synthesis of fine and high dispersed NMNPs. In this work, we propose the pyrazol-functional COFs strategy for the immobilization and uniform dispersion of NMNPs. Various M@COF-DAI (M = Pd, Ir, Pt) complexes are obtained with fine (1.74, 1.99 and 2.25 nm), uniform dispersed, and high metal content (20.47, 17.18, 29.46%) NMNPs. These NMNPs show high catalytic activity, excellent stability, and reusability in the p-nitrophenol reduction reaction. This results are superior to those NMNPs immobilized by other materials (e.g. graphene, MOFs, un-functionalized COFs), provide a high efficient immobilization strategy of NMNPs.
