dc.description.abstractEn este trabajo se sintetizaron los complejos cloruro de bis-[(4,4’-dicarboxi)-2,2’-biquinolina]cobre(I) (1) y [(4,4’-dicarboxi)-2,2’-bipiridina]diclorurocobre(II) (2), los cuales fueron enlazados covalentemente sobre la superficie de nanotubos de TiO2. Los respectivos complejos libres y los nanotubos se sintetizaron empleando condiciones hidrotérmicas. El proceso de anclaje de los respectivos complejos sobre el soporte se realizó bajo atmósfera inerte (N2), empleando una reacción de transesterificación entre los grupos carboxílicos de los sustituyentes presentes en el ligante y los grupos hidroxilos superficiales de los nanotubos de TiO2 previamente modificados por una reacción de sililación. Los nanotubos de TiO2 fueron caracterizados por microscopia SEM, espectroscopía Infrarroja (ATR-IR), Raman y UV-Vis en estado sólido, y sus propiedades texturales fueron determinadas por medidas de adsorción de N2. Los complejos de Cu libres y anclados sobre los nanotubos de TiO2 fueron identificados por espectroscopía Infrarroja (ATR-IR), Raman, Análisis Elemental, Difracción de Rayos X en polvo (DRXP) y espectroscopía fotoelectrónica de rayos X (XPS). La evaluación de su actividad fotocatalítica se estudió en la oxidación selectiva de alcoholes utilizando como molécula modelo el alcohol bencílico, empleando O2 molecular y luz visible. Con el desarrollo de esta propuesta se logró: 1- Obtener un sistema catalítico fotoactivo y estable para la oxidación de sustratos orgánicos precursores de productos industriales empleando catalizadores bioinspirados, 2-Avanzar en la frontera del conocimiento en procesos de activación del O2 molecular como agente oxidante amigable con el medio ambiente, 3- Avanzar en la identificación de potenciales centros activos y sistema catalíticos heterogéneos para la oxidación de moléculas orgánicas utilizando fuentes de energía alternativa que conlleve en el futuro a la renovación de tecnologías para la obtención de productos de una forma más eficiente y amigable con el medio ambiente (Texto tomado de la fuente).
dc.description.abstractIn this work, bis-[(4,4'-dicarboxy)-2,2'-biquinoline] copper(I) chloride (1) and [(4,4'-dicarboxy)-2,2'-bipyridine] dichloridecopper(II) (2) complexes were synthesized and covalently bonded on the surface of TiO2 nanotubes. The respective free complexes and nanotubes were synthesized using hydrothermal conditions. The anchoring process of the respective complexes on the support was performed under inert atmosphere (N2), employing a transesterification reaction between the carboxylic groups of the substituents present on the ligand and the surface hydroxyl groups of the TiO2 nanotubes previously modified by a silylation reaction. The TiO2 nanotubes were characterized by SEM microscopy, Infrared (ATR-IR), Raman and UV-Vis spectroscopy in solid state, and their textural properties were determined by N2 adsorption measurements. Free and anchored Cu complexes on TiO2 nanotubes were identified by Infrared (ATR-IR), Raman, Elemental Analysis, Powder X-ray Diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) spectroscopy. The evaluation of its photocatalytic activity was studied in the selective oxidation of alcohols using benzyl alcohol as a model molecule, using molecular O2 and visible light. With the development of this proposal it was accomplished: 1- To obtain a photoactive and stable catalytic system for the oxidation of organic substrates precursors of industrial products using bio-inspired catalysts, 2- To advance in the frontier of knowledge in processes of activation of molecular O2 as an environmentally friendly oxidizing agent, 3- To improve in the identification of potential active centers and heterogeneous catalytic system for the oxidation of organic molecules using alternative energy sources that will lead in the future to the renewal of technologies for obtaining products in a more efficient and environmentally friendly way.
