Rapid Synthesis of Hierarchical Porous Metal–Organic\nFrameworks and the Simulation of Growth

Abstract

Hierarchically\nporous metal–organic frameworks (HP-MOFs)\nhave been successfully synthesized under mild conditions within 60\ns using an anionic surfactant in a (Cu, Zn) hydroxyl double salt (HDS)\nsolution. The anionic surfactant served as a template for the construction\nof mesopores and macropores, and the (Cu, Zn) HDS accelerated crystal\nnucleation. Importantly, the growth of the HP-MOFs was monitored by\nattenuated total-reflectance Fourier-transform infrared spectroscopy,\nand the mechanism of synthesis was explored using mesodynamics (MesoDyn)\nsimulations. The introduction of larger pores into conventional MOFs\naided the diffusion of bulky molecules into the active center and\nenhanced the catalytic activity of the MOFs.
