TiO2 based Inorganic-Organic Hybrid Photocatalysts for Highly Selective Alcohol Partial Oxidation
2015
An integrated approach to develop a composite hybrid material made of titanium dioxide functionalized with an organic conjugated phenol (DIOL) and silver NPs suitable for the selective oxidation of water soluble aromatic alcohols to aldehydes in water under UV irradiation and very mild conditions was used. The 86% selectivity observed for the Rutile/DIOL/Ag composite is, to the best of our knowledge, the highest thus far reported for partial oxidation of aromatic alcohols to aldehydes in water suspensions of titanium dioxide. The method is general as it relies on the concomitant easier adsorption of the aromatic alcohol and more facile release of the aldehyde, coupled to fast interfacial el…
Solar heterogeneous photocatalysis for high added value molecules production
Photocatalytic and photoelectrocatalytic H2 evolution combined with valuable furfural production
2023
In this work the photocatalytic (PC) and photoelectrocatalytic (PEC) reforming of furfuryl alcohol (FA) under environmental friendly conditions was investigated. Both H2 evolution and partial oxidation to furfuraldehyde were followed. For the first time TiO2 based photocatalysts were studied and the photocatalytic activity of home prepared photocatalysts was compared with that of commercial ones under both UVA and simulated solar irradiation. PEC tests were performed by using home prepared TiO2 nanotubes (TiO2 NTs) as photoanode and Pt free Ni foam as cathode to improve the Hydrogen Evolution Reaction (HER). Both the partial FA oxidation reaction rate and H2 evolution rate were normalized f…

Hydroxamate Titanium–Organic Frameworks and the Effect of Siderophore-Type Linkers over Their Photocatalytic Activity
2019
The chemistry of metal–organic frameworks (MOFs) relies on the controlled linking of organic molecules and inorganic secondary building units to assemble an unlimited number of reticular frameworks. However, the design of porous solids with chemical stability still remains limited to carboxylate or azolate groups. There is a timely opportunity to develop new synthetic platforms that make use of unexplored metal binding groups to produce metal–linker joints with hydrolytic stability. Living organisms use siderophores (iron carriers in Greek) to effectively assimilate iron in soluble form. These compounds make use of hard oxo donors as hydroxamate or catecholate groups to coordinate metal Lew…

Controlled synthesis of linear and branched Au@ZnO hybrid nanocrystals and their photocatalytic properties.
2013
Colloidal Au@ZnO hybrid nanocrystals with linear and branched shape were synthesized. The number of ZnO domains on the Au seeds can be controlled by the solvent mixture. Imidazole-functionalized Au@ZnO hybrid nanocrystals were soluble in water and exhibited a greatly enhanced photocatalytic activity compared to ZnO nanocrystals. The pristine heterodimeric NPs were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV-Vis spectroscopy.
