A study of metal-organic framework sorption phenomena in solution.

Abstract

Metal-organic Frameworks (MOFs) are crystalline porous materials built up from metal ions or clusters connected with organic linkers through strong coordination bonds. Among the most outstanding properties their high porosity, large surface areas and tunable structures arise. In the chapters that make up this thesis, the three most relevant points in Materials Science converge: the synthesis, characterization and applicability of MOFs. On the one hand, the different parameters that affect the shape and shape of some well-known MOFs have been studied. In addition, a new characterization technique named Magnetic Sustentation has been developed for the quantification of adsorption processes taking place in solution, which allows a rapid and direct determination of the mass of captured targeted compounds by a paramagnetic MOF. Moreover, the behaviour of the high flexible MIL-88A(Fe) in the removal of short-chain alcohols from water has been theoretically and experimentally studied as well as the synergetic effect between the polymeric PVDF and MIL-88A(Fe) in prepared membranes. Finally, the first scientific effort to explore the true potentials of diverse kinds of MOFs for capturing CO2 in water has been done in order to set a benchmark in the field.
