Design,Synthesis And Characterization Of Hierachical Porous Materials Based On MIL-100(Sc) And MIL-100(Al)

Porous Metal-Organic Framework materials (MOFs) as a new member of the family of porous materials show superior performance than inorganic molecular sieves, particular in gas storage, owing to their advantages of high porosity, adjustable nano-pore structures. In recent years, they become the forefront topics, not only for the basic scientific research, but also for the potentially scientific applications.In this dissertation, we propose a simple and convenient synthetic strategy and successfully synthesize a series of hierachical porous materials based on MOFs, which pore size, pore volume and surface area are adjustable. This dissertation is written with two parts as follows:1. Design, synthesis and characterization of hierachical porous materials based on MIL-100(Sc):By changing the synthetic solvent and temperature of MIL-100(Sc), nano-MOF of MIL-100(Sc), named as HMOF-1is obtained. By using of inorganic salt as the template the hierachical porous materials based on HMOF-1, named as HMOF-2with micro-, meso-and macropores is gained.2. Synthesis and characterization of hierachical porous materials based on MIL-100(Al) with microporous:By changing the synthetic solvent and temperature of MIL-100(Al), nano-MOFs of MIL-100(Al), named as HMOF-3series are prepared.All above the materials are characterized by X-ray powder diffraction, IR, TEM, SEM and nitrogen adsorptions.
