Electro-oxidation of Ethanol on Carbon Supported PtSn and PtSnNi Catalysts [PDF]

, 2016
Even though platinum is known as an active electro-catalyst for ethanol oxidation at low temperatures (< 100 oC), choosing the electrode material for ethanol electro-oxidation is a crucial issue.

Three Stage Bleaching of Recycled Fibers Containing 30% Groundwood [PDF]

, 1978
A three stage bleaching sequence for a mixture of recycled chemical and groundwood fibers was investigated for maximum brightness increase. The three stages consisted of a reducing or color stripping stage, an oxidizing stage, and last a mild alkaline ...

Chemical reduction of hexavalent chromium (VI) in soil slurry by nano zero valent iron [PDF]

, 2015
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil

Magnetically Separable Ag/CuFe2O4 /Reduced Graphene Oxide Ternary Nanocomposite With High Performance for the Removal of Nitrophenols and Dye Pollutants from Aqueous Media

Acta Chimica Slovenica, 2018
In this work, a novel ternary magnetic nanocomposite namely Ag/CuFe2O4/rGO was produced by a facile solvothermal route. The reduction of graphene oxide (GO) to reduced form (rGO) and the in-situ deposition of CuFe2O4 and Ag nanoparticles on rGO occurred ...

Safety and Process Intensification of Catalytic Reduction of 4-Nitophenol Using Sodium Borohydride in Flow Microreactor System

Catalysts
In this work, a novel approach for the catalytic reduction of 4-nitrophenol to 4-aminophenol using sodium borohydride is proposed. It was shown that a continuous-flow microreactor system is an optimal tool for PdNP synthesis with dimensions of 3.0 ± 0.5 nm, as well as the performance of catalytic tests with high process efficiency, while keeping a high

Far-infrared spectroelectrochemistry: a study of linear molybdenum/iron/sulfur clusters [PDF]

, 2004
The far-infrared spectroelectrochemistry of linear M/Fe/S (M=Mo, W) complexes was investigated in methylene chloride and dichloroethane. With CsI as spectral windows, bands above 200 cm−1 can be observed in methylene chloride, except for a weak methylene

Theoretical study of C60 as catalyst for dehydrogenation in LiBH4

, 2011
Complex light metal hydrides possess many properties which make them attractive as a storage medium for hydrogen, but typically, catalysts are required to lower the hydrogen desorption temperature and to facilitate hydrogen uptake in the form of a ...

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Stereoselective synthesis of hydroxylated 3-aminoazepanes using a multi-bond forming, three-step tandem process [PDF]

, 2012
A multi-bond forming, three-step tandem process involving a palladium(II)-catalysed Overman rearrangement and a ring closing metathesis reaction has been utilised for the efficient synthesis of a 2,3,6,7-tetrahydro-3-amidoazepine.
