Abstract |
The synthesis of new micro- and meso-porous solids is an important field of
research worldwide. The diversity in their chemical and physical properties
originating from the chemical composition of inorganic or inorganic-organic
framework, structrure and porosity is responsible for their wide range of
technologically important applications.
In particular, catalysis and energy related applications are considered the most
important. Catalysis, either homogeneous or heterogeneous, plays and important role
to our modern society, because valuable products ranging from high value chemicals,
to polymers and gasoline are accessible at an industrial scale through catalytic
processes At the same time, energy consumption in our modern society is a real
concern because conventional energy sources (petroleum, natural gas and coal) are
directly associated with climate change including global warming among others.
The present thesis, deals with the synthesis and characterization of new porous
materials for application in heterogeneous catalysis (vanadium based catalysts) as
well as in selective hydrogen and CO2 storage (organo-silicates and graphene-based
materials).
The thesis includes four (4) chapters and an annex with information on the
techniques that were used. The first chapter includes the bibliographic review. In the
second chapter, the synthesis and characterization of mesostructure and mesoporous
vanadosilicates solid are reported, as well as a preliminary catalytic evaluation.
Chapter three and four deals with the synthesis and characterization of nanoporous
organosilica solids and carbon based materials, respectively. For these materials,
extensive hydrogen, CO2 and CH4 sorption studies were conducted.
All solids were fully characterized with a variety of experimental techniques,
including powder X-ray diffraction (PXRD), specific surface area and distribution of
porous, thermogravimetric analysis (TGA), elemental analysis (C, N, H), Raman and
FT-IR spectroscopy, UVvis/near IR diffuse reflectance spectroscopy, scanning
electron microscopy coupled with energy depressive spectroscopy (EDS) and
transmission electron microscopy (TEM).
