Photocatalytic oxidation of aromatic alcohols to aldehydes in aqueous suspension of home prepared titanium dioxide 2. Intrinsic and surface features of catalysts
(Elsevier Science BV, 2008)
In this paper some intrinsic electronic properties of home prepared (HP) TiO2 Catalysts were investigated by diffuse reflectance spectroscopy and quasi-Fermi level measurements. These powders were used for carrying out the ...
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 ...
Self-assembled titania-silica-sepiolite based nanocomposites for water decontamination
(Royal Soc Chemistry, 2009)
This work describes the preparation of microchannel structured monolithic pieces by the "ice-segregation induced self-assembly'' (ISISA) process. The monoliths exhibit a hierarchical structure composed of homogeneously ...
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 ...
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 ...
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 ...
Separation of catechins and methylxanthines in tea samples by capillary electrochromatography
(2009)
In this paper, the simultaneous separation of several polyphenols such as (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, theophylline, caffeine in green and black teas by capillary electrochromatography (CEC) was ...
The synthesis, characterization and structural analysis of a Co(III) complex of 1,10-phenanthroline and perfluorosebacic acid, [Co(HL)(phen) 2(H2O)]L·H2O
(Verlag der Zeitschrift fur Naturforschung, 2006)
The hexacoordinated mononuclear Co(III) complex 1, [Co(HL)(phen) 2(H2O)]L·H2O, with the mixed ligands (H2L = HO2C(CF2)8CO2H and 1,10-phenantroline) has been synthesized and characterized by elemental analysis, IR and UV/vis ...
Evaluation of polymer-supported rhodium catalysts in 1-octene hydroformylation in supercritical carbon dioxide
(American Chemical Society, 2003)
Supercritical CO2 has been used as a benign solvent in the hydroformylation of 1-octene using a Rh-based catalyst. The catalyst is attached to a polymer backbone that has fluoroacrylate branches that make it soluble in ...
Reverse atom transfer radical polymerization of stearyl methacrylate using 2,2'-azobisisobutyronitrile as the initiator
(2002)
The living/controlled radical polymerization of stearyl methacrylate was carried out with a conventional radical initiator (2,2'-azobisisobutyronitrile) in N,N-dimethylformamide in the presence of a 2,2'-bipyridine complex ...
