Hydrogenations are among the most important reaction class in the production of both bulk and fine chemicals. By adding hydrogen atoms to an organic compound, double or triple bond functionality is reduced, forming single bonds. In a single step, a hydrogenation reaction allows the form...
The selectivity in the hydrocarbon combustion reaction should provide the least CO2 and the most CO formation for a higher ISP value. In addition, combustion conditions should be provided to minimize unburned hydrocarbons in the exhaust gas composition. To reduce the formation of CO2 in the ...
The selectivity properties of the Pt-polyamide class are special, and only when a catalyst of this type is used can cyclohexene be found as a reaction product. On the basis of results obtained by different techniques, the presence on the polyamide surface of a bivalent platinum complex was ...

10−5 eV and 0.02 eV/Å, respectively. Cu and Pd featuring face-centred cubic (FCC) structure were used to calculate the reaction mechanism of MBY semihydrogenation, and their optimized lattice parameters (a = b = c) were 3.679 Å (Cu) and 3.972 Å (Pd),...
hybrid materials hold great promise for addressing a variety of environmental challenges. This review highlights recent advances in the design and synthesis of MOF-based materials, focusing on their potential as catalyst systems for the reduction of nitroaromatic compounds, a critical class of pollutants...
More importantly, unique self-assembly process often requires cetyltrimethylammonium bromide (CTAB) as a structure-directing template agent, in which the residual CTAB within its silicate network can offer as an additional phase-transfer function and can facilitate a two-phase asymmetric reaction that ...
Various types of metal ions and the ancillary ligands existing in the reaction determine the nature of the created products. Ligands have crucial impact on the region-, chemo-, and, of course, stereoselectivity in metal- catalytic processes[9], [10], [11]. The steric and electronic ...
Hydrogenation reactions are an important class of industrial reaction, which may be strongly influenced by gas-liquid mass transfer considerations. They are often carried out in a solvent in order to dissolve the reactant, to absorb heat of reaction and to solubilize coke precursors from the cataly...
The kinetic study was undertaken in a differential reactor mode, keeping the conversion of the reactant at less than 10%. The overall reaction was treated as comprising two separate reactions: first, the reduction of the nitro compound to hydroxylamine and then, the reduction of the hydroxylamine...
