There has been a limited number of aryl nitro reduction procedures via sonication reported in the literature,[8] although a recent study utilizing stannous chloride in the presence of ionic liquids provided aryl amines in good yields.[8a] Other procedures investigated the reduction of nitrobenzene using elemental iron,[8b] and reduction of some simple aryl nitro compounds using iron in the.

ORR in aqueous solutions occurs mainly by two pathways: the direct 4-electron reduction pathway from O 2 to H 2 O, and the 2-electron reduction pathway from O 2 to hydrogen peroxide (H 2 O 2). In non-aqueous aprotic solvents and/or in alkaline solutions, the 1-electron reduction pathway from O 2 to superoxide (O 2 -) can also by:

Enhanced electrocatalytic activity of nitrogen-doped multi-walled carbon nanotubes towards the oxygen reduction reaction in alkaline media Merilin Vikkisk, a Ivar Kruusenberg, a Sander Ratso, a Urmas Joost, b Eugene Shulga, b Ilmar Kink, b Protima Rauwel b and Kaido Tammeveski * aCited by:   The reason that Au() surfaces have exceptional activity toward the oxygen reduction reaction (ORR) in alkaline media has been a long-standing puzzle that remains unexplained.

Theoretically, the high activity of Au() cannot be understood entirely by the widely employed computational hydrogen electrode method, because oxygen adsorption on Au() is calculated to be Cited by: 2. Electrochemical reduction of nitrates and nitrites in alkaline media at constant current is rendered inoperable in the presence of hexavalent chromate.

Even at chromate concentrations as low as 9mgdm−3, the chromium hydroxide film, formed by the reduction of chromate, interferes with the reduction of nitrate and nitrite.

It remains a major challenge to develop a facile method to prepare non-noble metal electrocatalysts with high activity and durability to drive the sluggish oxygen reduction reaction (ORR) for proton exchange membrane fuel cells (PEMFCs).

Ni(OH) 2 also forms electrochemically on Ni electrodes in alkaline media, which has importance for the development of Ni-based electrocatalysts [23,[][][][]. compositions of the areas (A 1-A 2), (B 1-B 2) and (C 1-C 2) indicated in (a 3), (b 3) and (c 3), respectively.

In the potential region D — E from Fig. 1, there is an obvious reduction peak at − V on the CV curve and the corresponding mass increases order to clear the deposit in this potential region, the potentiostatic deposition was carried out at − V for iv) Reduction in alkaline medium.

Depending upon the nature of the reducing agent, nitrobenzene forms different products. v) Reduction with LiAlH 4. Aliphatic nitro compounds are reduced to p-amines with LiAlH 4. Aromatic nitro compounds on reduction with LiAlH 4 give azo compounds. An overview of some of the significant findings of surfactant adsorption research is presented.

Subjects include the importance of surfactant adsorption in petroleum applications, some history of surfactant adsorption research, the mechanisms which have been proposed to explain observed adsorption behavior, and a review of several significant surfactant adsorption by: In this work we studied the continuous electrooxidation of CO dissolved in M KOH electrolyte (COb) on Pt(hkl) at and K, respectively.

The results clearly demonstrate that Pt(hkl) electrodes in alkaline electrolyte represent a highly active system for COb oxidation. Significant reaction rates are observed even in the potential region for hydrogen underpotential deposition (Hupd).Cited by: The behaviour of cadmium and zinc in alkaline media has been investigated by several authors.

Most of these investigations have been accomplished on compact metal electrodes or on electrodes made from compacted metal powders; moreover, for the most part such works have been limited to the anodic behaviour of electrodes (1 to 10). SUMMARY Nitroaromatic compounds are xenobiotics that have found multiple applications in the synthesis of foams, pharmaceuticals, pesticides, and explosives.

These compounds are toxic and recalcitrant and are degraded relatively slowly in the environment by microorganisms.

2,4,6-Trinitrotoluene (TNT) is the most widely used nitroaromatic by: Vb2 Engineering Data Book 7 EDPM is not resistant to Hydrocarbons, Petroleum based oils, or Turpentine. If you have questions concerning other media contact your local Johnson Controls Representative. The temperature range of EDPM is minus 40°F to °F.

However, durometer hardness increases when temperature is consistently below 0°F. The Cover Feature illustrates the interplay between the activity for the oxygen evolution reaction and the battery charge state of LiMn 2 O 4 when used as a catalyst.

The electrocatalyst remains in the discharged battery state at pH 14, whereas a charged battery state is observed as manganese oxidizes at lower pH values, wich leads to catalyst deactivation.

A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text.

IN the development of an oxygen electrode for electrochemical fuel cells, it has been of interest to find effective catalysts for the decomposition of hydrogen peroxide in aqueous solutions of Cited by: Subsequent to the chronoamperometry, the electrode was then rinsed in argon saturated de-ionized water and transferred to another electrochemical cell (containing either M H 2 SO 4 solution to study copper monolayer in acidic media or M KOH to study oxidation of copper monolayer in alkaline media) for recording cyclic voltammogram.

Nitration of aniline in strong acidic medium also gives m-nitroaniline because. Inspite of substituents nitro group always goes to only m-position. In electrophilic substitution reactions amino group is meta directive. In acidic (strong) medium aniline is present as anilinium ion. In absence of substituents nitro group always goes to m-position.

Also, on the anode side, IrO 2 catalysts are more active in alkaline media than in other pH environment as previously reported. 44 Therefore, alkaline media not only works better for OER reaction on the anode, but also facilitates the CO 2 reduction reaction on the cathode, making it a highly suitable electrolyte for the electrochemical Cited by: followed by reduction of the nitro group to amine with reductive HI hydrolysis.

Parenthesis is a yield. In the literature, several methods for the reduction of nitro groups to amines have been reported. Aromatic amines are known to be produced by catalytic hydrogenation under continuous high pressure [24–27].Cited by: 7.
