Titania‐Coated Metal Nanostructures
Chemistry – An Asian Journal, 2012AbstractThe synergistic effect between metal and TiO2 nanoparticles brings about new, enhanced functionalities for a myriad of applications, ranging from labeling and sensing to catalysis and surface‐enhanced Raman scattering. Although extensive work has been done in the preparation of concentric TiO2‐coated metal nanostructures, current methods for ...

GOLD NANOPARTICLES, a relatively new class of surprisingly active supported catalysts, may owe key aspects of their catalytic prowess to the titania (TiO 2 ) support on which they are commonly dispersed, according to scientists in New Orleans ( J. Am. Chem. Soc. , DOI: 10.1021/ja907865t).

Olefins polymerization on titania and titania-supported rhodium
Catalysis Letters, 1991The adsorption of ethene and propene on titania and titania-supported rhodium has been studied, observing a continuous adsorption even after 24 h. The samples have been reduced at 623 or 773 K, but no difference was observed, whichever the reduction temperature or the presence of rhodium, on the amount of gas adsorbed per unit of surface area of the ...

Photocatalytic properties of titania nanostructured films fabricated from titania nanosheets
Physical Chemistry Chemical Physics, 2007We examined the photochemical properties of well-ordered multilayer films of titania nanosheets prepared on quartz-glass substrate using the layer-by-layer deposition method. The photocatalytic decomposition of gaseous 2-propanol and bleaching of Methylene Blue dye under UV light illumination were measured to evaluate the photocatalytic oxidation ...

Sol-Gel Titania and Titania-Silica Mixed Oxides Photocatalysts
Solid State Phenomena, 2010This paper presents a review of the work published by the authors on the synthesis, characterization and evaluation of the photocatalytic activity of TiO2/SiO2 materials. The use of titania-silica mixed oxides photocatalysts is proposed basically as a process improvement to overcome the difficulties of recovering titania from the slurries after the ...

Nanocellulose-Templated Porous Titania Scaffolds Incorporating Presynthesized Titania Nanocrystals
Chemistry of Materials, 2015Nanocrystalline cellulose (NCC) is an abundant biogenic nanomaterial with unique properties that enables the efficient synthesis of mesoporous crystalline titania. We significantly enhance the photocatalytic activity of titania thin films by introducing solvothermally synthesized preformed anatase nanoparticles into a sol–gel based biotemplated titania

Laccase immobilization on titania nanoparticles and titania-functionalized membranes
Journal of Membrane Science, 2014Abstract Bio-catalytic degradation of recalcitrant micropollutants with enzymes such as laccase provides an environmentally attractive alternative to the conventional filtration and adsorption processes. However, enzyme loss and denaturation remain key challenges for their potential use in water treatment applications.

Novel strategies towards mesoporous titania and titania-silicate composites
2004Abstract Two new pathways are developed to synthesize thermally stable and highly porous structures of nanosized anatase (titanium dioxide). The first is a new synthesis route towards mesoporous titania, based on an amine or CTABr-templating procedure.
