Sentence examples for mixed oxide particles from inspiring English sources
After reduction at 980°C and reoxidation at 900°C, the mixed oxide particles remained small and furthermore still remained single phase and homogeneous by XRD characterization.
Another important aspect is related to the unique microenvironment of MEs which results in specific interactions within the formed materials; this is particularly important for certain catalysts such as mixed oxide particles, conferring them with special properties and enhanced performance.
This paper describes the preparation, characterization and application of a composite electrode based on methylene blue adsorption to phosphorylated zirconia silica mixed oxide particles prepared by a sol gel process.
The mixed oxide particles seem to be necessary for the growth because they are often found at the tip inside the nanotube or also somewhere else in the middle of the tube as shown in Fig. 2c (marked with black spot).
The zeta potentials of mixed oxide particles in the presence and absence of PAA were measured with the Zetasizer 3000 laser zetameter (Malvern Instruments).
Comparison of specific activities (calculated as amount of ethanol converted per unit weight of active oxides) at the same space velocity demonstrated the size of mixed oxides particles as the important parameter for oxidation activity: decreasing in particle size led to increased catalysts efficiency.
The choice of a suitable Ru precursor and optimized activation conditions also allows the controlled preparation of small ruthenium particles on mixed oxide support to yield better results on glycerol hydrogenolysis on vapor phase reactions.
This phenomenon was studied both experimentally with catalytic N2O decomposition over Co La Al mixed oxide, and using a random particle distribution model.
In CLC of solid fuel, metal oxide particles are physically mixed and react with solid fuel at high temperature using gasification enhancer, such as steam, or CO2.
addition of dopants, stoichiometry of catalytic metal oxides and mixed metal oxides, particle size and shape.
While for cobalt-silicon mixed oxide, it seems that the uniform particle size distribution remains a delicate task with the normal sol-gel method or microemulsion methods [30 34].
