Homogeneous mixation at a molecular level makes seperation of the molecular catalyst extremely challenging and costly. It has been desired to find a supporting material designed in molecular level to anchor a single-atom catalyst and provide high degree of dispersion and substrate access in aqueous media. Here, we prepared discrete cages of metal-organic polyhedra anchoring single Pd atom [MOP-BPY(Pd)] and successfully performed a Suzuki-Miyaura coupling reaction with various substrates in aqueous media. The coupling efficiencies of the Suzuki-Miyaura coupling reaction exhibited more than 90.0 % for various substrates we have tested in the aqueous media, which is superior to those of the molecular Pd complex and metal-organic framework (MOF) anchoring Pd atoms. Moreover, MOP-BPY(Pd) was successfully recovered and recycled without performance degradation. |
