Cotton Fabric Immobilized AuNP@Graphene and ZnO@rGO for Heterogeneous Catalysis and Photocatalysis

Baruah B., Baruah S., West B., Baruah B., Baruah S., Kennesaw State University, US

The present study demonstrates liquid-phase exfoliation of graphene from pristine graphite in presence of surfactant and synthesis of reduced graphene oxide (rGO) via graphene oxide method. Pretreated cotton fabrics are primed with binder molecules before [...]

Modifications of graphitic C3N4 with multi-metal oxides for enhanced visible-light active photocatalysis

Masih D., Rohani S., University of Western Ontario, CA

Bulk graphitic C3N4 (g-C3N4) is a p-type semiconductor with band gap of 2.7 eV. For photocatalytic water splitting, valance and conduction band gap positions of g-C3N4 sandwich both oxygen and hydrogen evolution potentials, making g-C3N4 [...]

Reduced molybdenum oxide MoOx as a model catalyst for methanol photosynthesis from carbon dioxide and water

Silaev I.V., Khubezhov S.A., Tvauri I.V., Kaloeva A.G., Kibizov D.D., Ramonova A.G., Grigorkina G.S., Demeev Z.S., Bliev A.P., Sekiba D., Ogura S., Fukutani K., Magkoev T.T., North Ossetian State University, RU

Corresponding author, e-mail: t_magkoev@mail.ru (Tamerlan Magkoev) The work deals with the design of molybdenum oxide MoO2 with a specific density of anionic vacancies for methanol synthesis from carbon dioxide and water. Surface sensitive studies were [...]

Photocatalysis of Rhodamine B in water using nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

There are several techniques currently used for water organic contaminants removal, including Activated Carbon Adsorption, Chlorination, UV Photolysis, Ozonation, and Ferrate Oxidation. Although these techniques are useful in treating contaminated water, they have limitations in [...]

In-situ DRIFTS Studies on CuNi Catalyst for Ethanol Hydrogen Production

Kumar A., Ashok A., Bhosale R., AlMomani F., Tarlochan F., Qatar University, QA

Ethanol dehydrogenation mechanism was investigated over catalysts containing Cu and Ni metals prepared by solution combustion synthesis. In situ DRIFTS studies were conducted on individual metals (Cu and Ni) as well as on CuNi alloy [...]

Confinement Chemistry in Self-Assembling Polymer-Metal Nanoreactors

McTaggart M., Malardier-Jugroot C., Royal Military College of Canada, CA

We have developed and thoroughly characterized stable polymer-metal nanocomposite reactor systems with hydrophobic inner surfaces 2-3 nm apart. Previous work has shown that energetically unfavourable reactions, namely pyrrole polymerization and metal salt reduction, spontaneously occur [...]

Recycled PET Nanofibers Produced by Electrospinning Technique

Gomes S.S., Oliveira A.M., Maia A., Zanin M.H.A., Institute for Technological Research, Group for BioNanoManufacturing, BR

The universe of science and materials technology has been revolutionized with the development of materials at nanoscale, which contribute to the improvement of material properties and development of new materials, such as non-woven recycled polyethylene [...]

Dyes Adsorption on Cu3(BTC)2 Metal-Organic Framework

Loera-Serna S., Garcia-Ortiz J., Garcia-Ortiz J., Universidad Autónoma Metropolitana, MX

The present work suggests an alternative to the solution of environmental problems caused by the textile industry effluents, which contain natural dyes and non-biodegradable synthetic mostly. This solution is the use of porous metal-organic frameworks [...]

Effects of Engineered Nanoparticles on Hydrophobic Organic Pollutants

Sahle-Demessie E., Han C., Zhao A., Grecsek H., U.S. Environmental Protectin Agency, US

As nanomaterials become increasingly part of everyday consumer products, it is imperative to measure their potential release during production, use, and disposal, and assess their impact on the health of human and the ecosystem. This [...]
