Experimental and theoretical approach of nanocrystalline TiO2 with antifungal activity
Elsevier (2013-07-09)Using a solvothermal method for this research we synthesized nanocrystalline titanium dioxide (nc-TiO2) anatase particles with a mean diameter of 5.4 nm and evaluated their potential antifungal effect against planktonic ... -
Harnessing infrared photons for photoelectrochemical hydrogen generation. A PbS quantum dot based "quasi-artificial leaf"
American Chemical Society (2013)Hydrogen generation by using quantum dot (QD) based heterostructures has emerged as a promising strategy to develop artificial photosynthesis devices. In the present study, we sensitize mesoporous TiO2 electrodes with ... -
Hole Transport and Recombination in All-Solid Sb2S3-Sensitized TiO2 Solar Cells Using CuSCN As Hole Transporter
American Chemical Society (2012)All-solid semiconductor-sensitized solar cells lack models allowing their characterization in terms of the fundamental processes of charge transport and recombination. Nanostructured TiO 2/Sb 2S 3/CuSCN solar cells were ... -
Hydrazine sensors development based on a glassy carbon electrode modified with a nanostructured TiO2 films by electrochemical approach
Springer Verlag (2017)The authors describe a selective hydrazine sensor that is based on the use of a film of TiO2 nanoparticles faceted predominantly at the 101 and 001 sides. The hydrazine (Hyd) sensor was fabricated by depositing the ... -
Origin of efficiency enhancement in Nb2O5 coated titanium dioxide nanorod based dye sensitized solar cells
Royal Society of Chemistry (2011-05-13)Ordered one-dimensional metal oxides are considered promising architectures for dye-sensitized solar cells (DSC). Here we explore the properties determining the photovoltaic performance of DSC based on titanium dioxide ... -
Sb2S3-Sensitized Photoelectrochemical Cells: Open Circuit Voltage Enhancement through the Introduction of Poly-3-hexylthiophene Interlayer
American Chemical Society (2012)The Sb2S3-sensitized photoelectrochemical cells (Sb2S3–SPECs) in cobalt electrolyte were fabricated by depositing Sb2S3 on the macroporous TiO2 nanorods electrodes and consecutively spin-coating P3HT (Poly-3-hexylthiophene) ... -
Study of nanoparticles based on Cr and Sb doped TiO2 as pigments for inkjet technology applications
Elsevier (2015-05)Nanoparticles of the ceramic pigment with composition Ti0.97Cr0.015Sb0.015O2 were prepared by microemulsion-mediated solvothermal method at 180 ºC. Anatase or rutile single phase was obtained depending on the synthesis ... -
Three dimensional-TiO2 nanotube array photoanode architectures assembled on a thin hollow nanofibrous backbone and their performance in quantum dot-sensitized solar cells
Royal Society of Chemistry (2013-02-18)Facile synthesis of TiO2 nanotube branched (length [similar]0.5 μm) thin hollow-nanofibers is reported. The hierarchical three dimensional photoanodes (H-TiO2-NFs) (only [similar]1 μm thick) demonstrate their excellent ... -
Unraveling the Mechanisms of the Selective Oxidation of Methanol to Formaldehyde in Vanadia Supported on Titania Catalyst
American Chemical Society (2010)A computational study based on B3LYP calculations was carried out to investigate the kinetic and mechanistic aspects of the selective oxidation of methanol to formaldehyde using titania-supported vanadate as a catalyst ...
