TL;DR: In this article, the antioxidant-rich fractions were extracted from grape seeds (Vitis vinifera) using various solvents, such as acetone, ethyl acetate, methanol, and mixtures of different Solvents such as EtOAc and water in 9:1, 17:3 and 4:1 ratios.

TL;DR: The results suggest that the reduction of metal ions and stabilization of the resultant particles in the first two solutions involved the same class of biomolecules, including flavonoids, which were present in comparable amounts in both the tea leaf broth and ethyl acetate extract, but are absent in the CH(2)Cl( 2) extract of tea leaves.

TL;DR: In this paper, a urea combustion method was used to evaluate the performance of a mixture of CuO and CeO 2 catalysts in the oxidation of ethanol, ethyl acetate and toluene.
Abstract: CuO–CeO 2 catalysts were prepared via a urea combustion method and their performance in the oxidation of ethanol, ethyl acetate and toluene was evaluated. XRD, H 2 -TPR and N 2 physisorption were employed in catalyst characterization. The specific surface area of mixed materials was higher than the one of single oxides. In ceria-rich materials, crystalline copper oxide phases are absent and segregation of a CuO phase takes place at atomic Cu/(Cu + Ce) ratios higher than 0.25. The mixed oxides get reduced by H 2 at lower temperatures than the corresponding single oxides and copper ions promote reduction of ceria. Ethanol gets more easily oxidized than ethyl acetate, which in turn gets more easily oxidized than toluene. CuO–CeO 2 catalysts of low copper content produce very low amounts of acetaldehyde during ethanol and ethyl acetate oxidation at all conversion levels. This is augmented by the presence of water in the feed. The specific activity of Cu x Ce 1− x catalysts in the oxidation of ethanol, ethylacetate and toluene (specific rate of volatile organic compound (VOC) consumption) is lower than the one of pure CuO and CeO 2 , i.e. combination of the two phases leads to suppression of intrinsic activity. On the other hand, the specific rate of CO 2 production during ethanol and ethyl acetate oxidation is also lower over CuO–CeO 2 than over CeO 2 , but higher than over CuO. The larger surface area of CuO–CeO 2 catalysts counterbalances their smaller specific activity allowing complete VOC conversion at lower temperatures compared to the single oxides.

TL;DR: In this paper, the photooxidation rate of 22 organic solutes over a UV illuminated film of Degussa P25 titanium dioxide was studied over a 100-fold concentration range for each solute, generally from about 1 to 100 mg liter−1.

TL;DR: A detailed summary of recent advances in catalytic conversion of ethanol to a wide range of chemicals and fuels can be found in this article, where the authors particularly focus on catalyst advances and fundamental understanding of reaction mechanisms involved in ethanol steam reforming.
Abstract: With increased availability and decreased cost, ethanol is potentially a promising platform molecule for the production of a variety of value-added chemicals. In this review, we provide a detailed summary of recent advances in catalytic conversion of ethanol to a wide range of chemicals and fuels. We particularly focus on catalyst advances and fundamental understanding of reaction mechanisms involved in ethanol steam reforming (ESR) to produce hydrogen, ethanol conversion to hydrocarbons ranging from light olefins to longer chain alkenes/alkanes and aromatics, and ethanol conversion to other oxygenates including 1-butanol, acetaldehyde, acetone, diethyl ether, and ethyl acetate.
