Nitrogen-doped carbon nanotubes : controlled synthesis, physicochemical characterization and application as Pd catalyst supports in a hydrogenation reaction.
(2015)Catalysis is a fundamental pillar in the development of a sustainable economy that is in line with the principles of green chemistry. This drives the need to develop novel catalytic systems whose activity and selectivity ... -
Organic flame retardants in the indoor environment.
(2016-04-08)Flame retardants (FRs) have become ubiquitous contaminants found in humans, animals, various outdoor environments, e.g. air, soil, sediment, etc., and indoor environments particularly, homes, automobiles, classrooms and ... -
Oxidation and oxidative dehyrogenation of n-octane using V₂O₅ supported on hydroxyapatites.
(2012)Vanadium pentoxide with loadings varying from 2.5-15 wt% was supported on hydroxyapatite (HAp) by the wet impregnation technique. The materials were characterized by techniques such as X-ray powder diffraction (XRD), ... -
Oxidation of ɳ-octane over molybdenum oxide based catalysts.
(2016-04-11)The research into alternative feedstocks has gained importance in recent years to replace olefins by alkanes. The use of alkanes is viable since they are cheap, abundant and can be easily sourced from Gas to liquid (GTL) ... -
Oxidative degradation of textile dyes with hypochlorite and chlorine dioxide.
(2010)The oxidation reaction mechanisms of water soluble textile dyes amaranth (an azo dye), brilliant blue-R (a triaryl dye) and safranine-O (an azine dye) with oxidants- hypochlorite and chlorine dioxide, were investigated. ... -
The oxidative dehydrogenation of n-Hexane and n-Octane over vanadium magnesium oxide catalysts.
(2006)Vanadium magnesium oxide (VMgO) catalysts with different vanadium loadings were synthesized and tested for catalytic activity using pure «-hexane and «-octane as feeds. High surface area catalysts were obtained by the wet ... -
Oxidative dehydrogenation of n-octane over molybdate based catalysts.
(2014)The oxidative dehydrogenation of n-octane over different molybdates was investigated using a continuous flow fixed bed reactor in the temperature range of 350-550 °C at 50 °C intervals. Molybdates investigated in this ... -
Oxidative dehydrogenation of n-octane using vanadium-based hydrotalcite-like compounds.
(2010)The oxidative dehydrogenation of alkanes provides a potential route to higher value products such as olefins and aromatic compounds. Alkanes are of low environmental impact and their increasing availability has prompted ... -
Oxidative reactions to form ethyl methacrylate via a phase specific iron phosphate catalyst .
(2012)The importance of alkyl methacrylates has been firmly established within the chemical industry. For example, free radical polymers, which contain the methacrylate backbone are more rigid than acrylate polymers. Several ... -
