MnOx catalysts with different morphologies for low temperature synergistic removal of NOx and toluene: Structure–activity relationship and mutual inhibitory effects - ScienceDirect JavaScript is disabled on your browser. Please enable JavaScript to use all the features on this page. Skip to main content Skip to article The simultaneous catalytic removal of x ) and toluene, in an existing selective catalytic reduction (SCR) unit, has drawn much attention. Exploring the interaction effects between the catalytic x is crucial to ensure the successful design and development of catalysts for their simultaneous removal. MnO x x nanocuboid were synthesized to compare their catalytic performances for the simultaneous removal of NO x and toluene. The MnO x nanorod catalyst possessed greater x nanocuboid catalyst and exhibited a greater than 85% catalytic activity in the simultaneous abatement of NO x and toluene at 275 °C. The MnO x nanorod catalyst had a higher proportion of Mn 4+ and a better redox ability compared with the MnO x nanocuboid, resulting in an excellent catalytic activity. Thus, it was selected as a model catalyst to investigate the interaction effects. Compared with the separate NH 3-SCR and toluene oxidation reactions, there was a mutual inhibitory effect between the SCR reaction and toluene oxidation in the simultaneous removal process over the model catalyst (MnO x nanorod). This mutual inhibitory effect was investigated systematically using in situ DRIFTs. Mutua...

\( \newcommand\) • • • • • • • • Arenes are aromatic hydrocarbons. The term "aromatic" originally referred to the pleasant smells given off by arenes, but now implies a particular type of delocalized bonding (see below). The arenes you are likely to encounter at this level are based on benzene rings. The simplest of these arenes is benzene itself, C 6H 6. The next simplest arene is methylbenzene (common name: toluene), which has one of the hydrogen atoms attached to the ring replaced by a methyl group - C 6H 5CH 3. The structure of Benzene The structure of benzene is covered in detail on two pages in the organic bonding section of this site. It is important to understand the structure of benzene thoroughly to understand benzene and methylbenzene chemistry. Unless you have read these pages recently, you should spend some time on them now before you go any further on this page. This diagram shows one of the molecular orbitals containing two of the delocalized electrons, which may be found anywhere within the two "doughnuts". The other molecular orbitals are almost never drawn. • Benzene, C 6H 6, is a planar molecule containing a ring of six carbon atoms, each with a hydrogen atom attached. • The six carbon atoms form a perfectly regular hexagon. All of the carbon-carbon bonds have exactly the same lengths - somewhere between single and double bonds. • There are delocalized electrons above and below the plane of the ring. • The presence of the delocalized electrons makes benz...

Toluene - C6H5CH3 What is Toluene? Toluene is a clear, colourless liquid with a benzene-like odour. The 6H 5CH 3. Toluene is a naturally occurring compound derived primarily from petroleum or petrochemical processes. Toluene is a common component in gasoline, glues, and paint products. Toluene is a liquid, which is colourless, water-insoluble and smells like paint thinners. It is a mono-substituted colourless liquid, consisting of a CH 3 group that is attached to a phenyl group. Table of Contents • • • • • • • • Properties of Toluene Toluene is more reactive to electrophiles than 2 in the presence of FeCl 3 to give ortho and para isomers of chlorotoluene. Chemical formula of Toluene C 6H 5CH 3 Boiling point of Toluene 111 °C Melting point of Toluene −95 °C Density of Toluene 0.87 g/mL Molecular weight of Toluene 92.141 g/mol Toluene structure Toluene is widely used as an industrial raw material and a solvent for manufacturing many commercial products, including paints and glues. Toluene Production Toluene is naturally found in crude oil and as a by product in gasoline production. Also, it is obtained as a by product in coke production from coal. Production of Toluene at the industrial level is inexpensive. It is synthesized in various methods. For example, the reaction of benzene with methyl chloride in the presence of aluminium chloride ( C 6H 5H + CH 3Cl → C 6H 5CH 3 + HCl Toluene Uses Toluene is widely used as a precursor to benzene.

The structures of all three components of one such system, the toluene 2,3-dioxygenase system, have now been determined. This system consists of a reductase, a ferredoxin and a terminal dioxygenase. The dioxygenase, which was cocrystallized with toluene, is a heterohexamer containing a catalytic and a structural subunit. The catalytic subunit contains a Rieske [2Fe-2S] cluster and mononuclear iron at the active site. This iron is not strongly bound and is easily removed during enzyme purification. The structures of the enzyme with and without mononuclear iron demonstrate that part of the structure is flexible in the absence of iron. The orientation of the toluene substrate in the active site is consistent with the regiospecificity of oxygen incorporation seen in the product formed. The ferredoxin is Rieske type and contains a [2Fe-2S] cluster close to the protein surface. The reductase belongs to the glutathione reductase family of flavoenzymes and consists of three domains: an FAD-binding domain, an NADH-binding domain and a C-terminal domain. A model ...
