Nanostructured rutile TiO2 for selective photocatalytic oxidation of aromatic alcohols to aldehydes in water
(American Chemical Society, 2008)
Selective photocatalytic oxidation of aromatic alcohols to aldehydes was performed in water in the presence of TiO2 rutile photocatalysts that exhibited a low degree of crystallinity. The nanostructured rutile samples, ...
Kinetics of 4-Methoxybenzyl Alcohol Oxidation in Aqueous Solution in a Fixed Bed Photocatalytic Reactor
(American Chemical Society, 2010)
The photocatalytic oxidation of 4-methoxybenzyl alcohol in water was performed in a fixed bed continuous annular reactor by using a home-prepared TiO2 catalyst supported on Pyrex glass beads. The investigation was aimed ...
Photocatalytic oxidation of aromatic alcohols to aldehydes in aqueous suspension of home-prepared titanium dioxide 1. Selectivity enhancement by aliphatic alcohols
(Elsevier Science BV, 2008)
Oxygenated aqueous suspensions of home-prepared (HP) and commercial TiO2 catalysts were used in a batch photoreactor for carrying out the oxidation of benzyl alcohol (BA) and 4-methoxybenzyl alcohol (MBA) under different ...
Photocatalytic degradation of 4-nitrophenol in a continuous reactor containing titanium dioxide supported on glass beads
(Walter De Gruyter GMBH, 2008)
The photocatalytic degradation of 4-nitrophenol in aqueous solution was per-formed by using a continuous fixed bed annular photoreactor. Titanium dioxide was used as the photocatalyst, supported as thin film on Pyrex glass ...
Photocatalytic selective oxidation of 4-methoxybenzyl alcohol to aldehyde in aqueous suspension of home-prepared titanium dioxide catalyst
(Wiley-V C H Verlag GMBH, 2007)
The photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde (PAA) was performed in water with organic-free suspensions of home-prepared and commercial titanium dioxide (TiO2) catalysts. The nanostructured ...
Selective photocatalytic oxidation of 4-substituted aromatic alcohols in water with rutile TiO2 prepared at room temperature
(Royal Soc Chemistry, 2009)
Home-prepared (HP) rutile TiO2 catalysts were prepared at room temperature by using H2O and TiCl4 in different ratios and without addition of additives. The catalysts were used for carrying out the selective photocatalytic ...
Environmentally Friendly Photocatalytic Oxidation of Aromatic Alcohol to Aldehyde in Aqueous Suspension of Brookite TiO(2)
(Springer, 2008)
Photocatalytic oxidation of 4-methoxybenzyl alcohol to aldehyde in water has been achieved by using home-prepared uncalcined brookite TiO(2). Three different lamp irradiances have been applied in order to check the influence ...
Graphite-supported TiO2 for 4-nitrophenol degradation in a photoelectrocatalytic reactor
(Elsevier Science Sa, 2009)
Amorphous TiO2, prepared at room temperature through a sol-gel method implementing hydrolysis of TiCl4, has been supported on graphite rods and then annealed at 673 K. In this way graphite was completely covered by a porous ...
Photocatalytic oxidation of nitrobenzene and phenylamine: Pathways and kinetics
(John Wiley & Sons Inc, 2007)
The oxidation of nitrobenzene and phenylamine has been carried out by heterogeneous photocatalysis in aqueous suspensions of commercial TiO2. The photoreactivity results indicate that two reaction pathways occur in parallel ...
A quantitative method of photoadsorption determination for irradiated catalyst in liquid-solid system
(Elsevier Science BV, 2009)
A method for determining the amount of substrate adsorbed onto the catalyst surface in liquid-solid photocatalytic system under reaction conditions (photoadsorption) is proposed. The method has been applied to the ...
