Synthesis And Characteration Of Mesoporous Metal-Organic Frameworks Based On HKUST-1?MIL-101 And MIL-88

Owing to various structures,high porosity,excellent tunable functionality and higher surface areas,Metal-organic framework materials are potentially applied to molecule separation,gas storage,catalysis,proton conduction,magnetic material.Unlike the use of extension of the ligand to increase the pore size of mesoporous metal-organic framework materials(mesoMOFs),we developed a strategy to construct permanent interparticle porosity based on nanoscale metal-organic framewoks(NMOFs)regulate the pores by adjusting some parameters,that attained a series of sinterparticle porosity dominated mesoMOFs(IPD-mesoMOFs)from five MOF-types with HKUST-1,MIL-101(Cr),MIL-101NDC(Cr),MIL-101BPDC(Cr)and MIL-88(Fe)termed as IPD-mesoMOFs-3,IPD-mesoMOFs-6,IPD-mesoMOFs-7,IPD-mesoMOFs-8 and IPD-mesoMOFs-12,respectively.This dissertation contains four parts as follows:1.Synthesis of IPD-mesoMOFs-3 based on HKUST-1: the polymorphs of IPD-mesoMOFs-3 were obtained and show intercrystalline mesopores ranging from 2.0 nm to19.0 nm.2.Synthesis of IPD-mesoMOFs-(6-7)based on MIL-101(Cr): the polymorphs of IPD-mesoMOFs-(6-7)were obtained,and the tunable mesopore apertures(range 4.57nm-42.98 nm),higher surface area.3.Synthesis of IPD-mesoMOFs-6(Fe)based on MIL-101(Fe): the polymorphs of IPD-mesoMOFs-6(Fe)were obtained.4.Synthesis of IPD-mesoMOFs-12 based on MIL-88(Fe): the polymorphs of IPD-mesoMOFs-12 were obtained,and the tunable mesopores apertures up to 29.396 nm.The IPD-mesoMOFs were characterized by PXRD,nitrogen adsorption,IR,SEM and TGA.
