Sentence examples for mixed oxide systems from inspiring English sources
We have characterized two different distinct systems, Argon clusters and mixed oxide systems, for analysis.
This catalyst was selected from our earlier work on methane to methanol conversion over mixed oxide systems.
The oxidation of toluene, p-methoxytoluene and p-terbutyltoluene has been examined on several mixed oxide systems, based on molybdates, telluromolybdates and vanadia-titania catalysts.
This review deals with an analysis of the main structural and reactivity properties of mixed oxide systems containing vanadium oxide as the key component in catalysts for gas-phase reactions, mainly oxidations.
Mg/Mn/Al mixed oxide systems of similar atomic ratios close to 2/0.5/1 were obtained by calcination of Mg,Al layered double hydroxide (LDH) type precursors containing Mn either in the cationic form within the brucite layer or as permanganate anions in the interlayer.
However, the influence of structural variety and chemical complexity in the mixed oxide systems on catalytic performance is difficult to distinguish.
Our screening programme showed that supported Cu/Cr oxide catalysts are most effective for CO oxidation and NO reduction by CO, and this mixed oxide system was studied further.
For a mixed oxide system (rutile-TiO2 and MgO), our results indicate that size, dimensions and structural stability of oxide nano-structures play an important role during sintering.
Attractive interactions between anionic tungstate units (of the inner WO3 layer) and cationic oxo-zirconium surface species (existing in acid media on ZrO2 nanostructures in the outer layer) tend to stabilize the mixed oxide system.
These results are consistent with nanoparticles previously synthesized by the coprecipitation of the Fe(II), Fe III), and Gd III) salts in the same basic solution, which did not result in a mixed oxide system, Gd2O3-Fe3O4, but a doped Gd:Fe3O4[55].
Typical single-source precursors for sol gel processing are bimetallic alkoxides in which the two metals are bridged by alkoxo groups, which are then lost upon sol gel processing (i.e., upon formation of mixed-oxide systems).
