Microwave-assisted hydrothermal synthesis of Cu-doped titanate nanotubes: photoluminescence and photocatalysis properties

Manfroi D.C., Andrade L.P., Cavalheiro A.A., Jos A.A., Teixeira G.F., Perazolli L.A., Varela J.A., Zaghete M.A., Universidade Estadual Paulista, BR

Alkali titanates have been intensively investigated mostly because of their properties. And the interest for transition metal doping of 1D titanate nanostructures is enormous, especially copper. In the present work we report the synthesis of [...]

Development of a hydroprocessing catalyst containing Boron and Nano-boron compounds

Yonel-Gumruk E., Meric Kartal Berker A., Özcan O., Nilgün Akin A., Turkish Petroleum Refineries Corporation, US

Hydroprocessing is a refinery process of catalytic cracking and hydrogenation of petroleum in order to convert low value heavy hydrocarbons into high value light hydrocarbons and to remove sulphur, nitrogen, oxygen and metals to the [...]

Voltammetric and Impedance studies of Phenols and Its Derivatives at Carbon Nanotubes/Prussian Blue Films Platinum Modified Electrode

Adekunle A.S., Arotiba O.A., Agboola B.O., Maxakato N.W., Mamba B.B., Ebenso E.E., North-West University, ZA

Phenols and the chlorinated and alkylated derivatives are classified as priority pollutants due to the health risk associated with their toxicity. Due to their constant presence in industrial waste and consequently their carcinogenic risk for [...]

Application of alumina-based nanogold catalysts in gas mask and CO2 laser

Qi C., Su H., Sun X., Guan R., Lin H., Sun X., Zheng Y., An L., Yantai Univeristy, CN

We have found that Au nanoparticles on Al2O3 (a popular commercially available support material) show surprisingly high activities for CO oxidation when properly prepared [6-11]. Our proprietary catalyst, Au deposited on a ferrite-modified alumina prepared [...]

A highly dispersed Cu-Ni/Ce0.5Zr0.5O2/SBA-15 nanocatalysts: Preparation, characterization and the catalytic application in direct synthesis of dimethyl carbonate

Yang M., Zhang Z-q, Chang Q-Q, Liu E-Z, Liu Y., Zhao B., Liu E-Z, Liu Y., Hu X.Y., Fan J., Northwest University, CN

SBA-15 has been successfully applied as a support to prepare supported metal catalysts[1]. Nevertheless, Conventional impregnation method cannot assure the incorporation of active species into SBA-15 mesopores. The modification of silica support using ethylene glycol [...]

Enantioselective desymmetrization of meso-cyclopent-2-en-1,4-diacetate to 4-(R)-hydroxycyclopent-2-en-1-(S)-acetate using enzyme immobilized superparamagnetic nanocomposites

Eizadi Sharifabad M., Sen T., University of Central Lancashire, UK

Enzymes are well established as catalysts for various bio-transformations. However, it is difficult to remove the expensive enzymes from the reaction mixtures. Hence, immobilization of enzymes on solid support is a very important step for [...]

Differentiating electro-catalytic reaction of hydride with respect to a non-Pt catalyst morphology based on first-principles: extended surfaces versus nanoparticles

Sison Escaño M.C., Lacdao Arevalo R., Kasai H., University of Fukui, JP

One of the attractive hydride compounds is the borohydride which exhibits high hydrogen content in NaBH4 form (~10.6 wt%). Thus, significant number of experimental research have been devoted to investigate its applicability as a hydrogen [...]
