Homogeneous catalysis is a type of catalysis in which the catalyst operates in the same phase as the reactants — usually dissolved in a solvent. Mechanistic studies of homogeneous catalysts are generally easier than those of heterogeneous catalysts, which aids optimization. They can, however, be ...
Define homogeneous. homogeneous synonyms, homogeneous pronunciation, homogeneous translation, English dictionary definition of homogeneous. of the same kind or nature; unvarying; unmixed: a homogeneous population Not to be confused with: homogenous – al
Paired electrocatalysis unlocks cross-dehydrogenative coupling of C(sp3)-H bonds using a pentacoordinated cobalt-salen catalyst Cross-dehydrogenative coupling (CDC) of C-H bonds is an ideal approach for C-C bond construction but suffers from low selectivity of similar C-H bonds. Here, the autho...
Choplin and Quignard [4] make, however, a precise definition: the immobilized species can be the original homogeneous catalyst with its coordination sphere highly preserved, or a variant of the original complex because the anchoring takes place via a direct bond between the metal center and a ...
oxygen-containing organiccompounds. Acobaltcarbonyl catalyst Co2(CO)8is employed; this hydrocarbon-soluble catalyst is believed to activate hydrogen by formation of HCo(CO)4, which then reacts with the olefin. This reaction has led to a number of studies of organometallicchemistry.Copper,silver, ...
Comparison of Fixed and Fluidized Bed Reactors in the Steam Reforming of Raw Bio-oil with NiAl2O4 Derived Catalyst This work compares the performance of fixed and fluidized bed reactors in the SR of raw bio-oil with a NiAl2O4 spinel derived catalyst, which has high acti... Landa, Leire,...

The homogeneous distribution of such pores within the material is also a key parameter in order to obtain better diffusion within the catalyst [9]. In fact, when the diffusion is the controlling step of the overall reaction, improvements at the active sites would not significantly increase the ...
2.1 Catalyst preparation CaTiO3 samples were prepared by three methods, i.e., co-precipitation method (CP), homogeneous precipitation method (HP) and solid-state reaction method (S). In the co-precipitation method, CaCl2·2H2O (Wako, 99.9%, 5.4 g) and TiCl4 HCl solution (Wako, 16–17%...
