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 ...

The photocatalytic activity of titanium dioxide is sometimes observed to increase upon addition of silica, but the origin of this enhancement is not clear. To shed light on this effect, we investigate the titania/silica system in case of perfect segregation using density functional theory.

Cellulose acetate, cellulose nitrate, polyamide, polyethersulfone and polypropylene membranes have been used as templates in which sol–gel chemistry was conducted to fabricate porous metal oxide films. Dilution of the metal alkoxide solution allowed for variation in the total amount of inorganic deposited per membrane.

AbstractEmploying anatase TiO2 nanocrystals with predominantly {0 0 1} facets, anatase TiO2 nanocrystals with predominantly {1 0 0} facets, and TiO2 P25 with predominantly {1 0 1} facets as supports, we have comprehensively studied the morphology effect of TiO2 on the Au‐TiO2 interaction, structure, and catalytic performance of Au/TiO2 catalysts in ...

Fabrication of silica-on-titania and titania-on-silica nanoparticle assemblies
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2007Abstract Structures of silica particles on a titania surface and titania particles on a silica surface were formed by deposition of SiO2 or TiO2 nanoparticles on pre-patterned substrates. Photolithography was used to create a matrix for the selective deposition of nanoparticles by immersion in a colloidal suspension.

The study of photocatalytic activities of titania and titania–silica aerogels
Applied Catalysis B: Environmental, 2003Abstract Titania and titania–silica aerogels have been prepared by sol–gel method. The pH of their point of zero charge (pHPZC), SBET, volumes of the micro- and mesopores were determined. Considering titania–silica aerogels FTIR analyses were carried out. Three phenol para-derivatives (p-chlorophenol, p-nitrophenol, 4-hydroxybenzoic acid) were chosen

Laccase immobilization on titania nanoparticles and titania-functionalized membranes
Journal of Membrane Science, 2014Bio-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.

HE role of Bottom in A Midsummer Night's Dream reaches its climax in his meeting with Titania. Here the image is engendered which is most likely to linger in the mind even when other essentials of the play have grown hazy: ass-headed Bottom in the arms of the Fairy Queen.
