Redox catalysts based on Au and Pd/PdO bimetallic nanoparticles confined in mesoporous silica SBA-15

Dias B.F., Teixeira-Neto A.A., Teixeira-Neto E., Teixeira-Neto A.A., Teixeira-Neto E., Universidade Federal do ABC, BR

Since the catalytic activity of nanoscale gold was discovered many studies in this subject have been done. A very interesting system, based on Au and Pd bimetallic nanoparticles (NPs), has emerged from those studies, and [...]

Copper Oxide–Cobalt Oxide Nanoscale Heterostructures for Photocatalysis

Shi W., Chopra N., The University of Alabama, US

The research work discussed here will be focused on development of multifunctional nanoscale heterostructured photocatalysts comprised of oxides of copper and cobalt. Two fabrication approaches are described: a) solution and b) dry processing route. The [...]

Effects of Preparation Methods and Electronic States of the AuPd Bimetallic Nanoparticles on the Activity for Aerobic Oxidation of Alcohols

Nishimura S., Yakita Y., Katayama M., Higashimine K., Ebitani K., Japan Advanced Institute of Science and Technology, JP

Bimetallic nanoparticles (NPs) have attracted great interests and potentials in advanced nancatalysts because they achieved unique catalytic performances different from those of monometallic NPs. However, the contributions of their morphologies and/or electronic states to the [...]

Extraordinary Activity of Nanodispersed Bimetallic NiFe Phosphide Catalysts for the Conversion of a Biomass Model Compound

Oyama S.T., Cho A., Shin J., Takagaki A., Kikuchi R., The University of Tokyo, JP

The present work deals with the development of new catalysts, transition metal phosphides, which have outstanding activity for hydrodeoxygenation of pyrolysis oil. The study is significant as it leads to the production of high-energy content [...]

Synthesis and characterization of magnetic manganese ferrites using a simple combustion method and its application in removal of organics

Desai I., Mills M., Nadagouda M., Elovitz M., Boulanger B., U.S. Environmental Protection Agency, US

Ferrospinels have been shown to have promising oxidative and catalytic properties. Our research focuses on novel magnetic manganese ferrite catalysts which have been developed and thoroughly characterized. Their potential application as oxidative catalysts/sorption in removal [...]

Magnetically Recyclable Nanocatalysts: Eco-friendly Solutions for Green Catalysis

Pereira C., Rocha M., Fernandes C., Rebelo S.L.H., Freire C., Porto University, PT

In the last decades, the global concern for environment protection boosted the development of cost-effective eco-friendly catalytic processes. Magnetic nanoparticles emerged as a new generation of catalysts or catalyst supports owing to their nanosize, easy [...]

Nano-Organocatalysts: new magnetically retrievable tools for enantioselective synthesis

Nehlig E., Motte L., Guénin E., Université Paris, FR

We report the elaboration of new organocatalyst functionalized superparamagnetic iron oxide nanoparticles that can act as a new enantioselective organocatalyst. Differents organocatalysts are grafted using two different methodologies on a nanoplateform constituted of 10 nm [...]

Nanobiotechlogy: Applications in Food Science and Engineering

Sadeghi R., Ansari S., Uzun S., Bozkurt F., Gezer P.G., Karimi M., Kokini J., University of Illinois at Urbana-Champaign, US

Quantum (QD) dots were conjugated to anti-gliadin antibody and used as a fluorescent probes to track gliadin protein in dough and baked bread samples. CLSM images showed significant changes in the distribution of gliadin within [...]

Gold Nanorods: A Journey Towards Successful Synthesis

Kolb A.N.D., Johnston J.H., Victoria University of Wellington/MacDiarmid Institute for Advanced Materials and Nanotechnology, NZ

Gold nanorods (AuNRs) are attracting substantial research interest due to their remarkable size- and shape-related optical properties. AuNRs in solution are brightly coloured but not golden whereby the precise colours of AuNRs depend on accurately [...]

Practical synthesis of nanomaterials and nanostructures

Rae A., Matteson J., Dansoh V., NanoMaterials Innovation Center, US

Nanoparticle and nanostructured coating synthesis is commonly hampered by complex processes or the need to use precursors which may not yet be registered under TSCA or REACH. There are, however, simple and practical processes using [...]
