“…These results suggest that the incorporation of Ru to SrTiO 3 could prevent particles sintering during the calcination step at 800°C. It is thus confirmed that the microwave-assisted preparation method can save energy and time due to the faster kinetics of crystallization [29].…”

“…According to Spanier et al [71], a large number of factors can contribute The position and the FWHM for the F2g band, and the relative intensity ratio of ID/IF2g ceria-based catalysts are shown in Table 4. In general, the ratio of ID/IF2g, where IF2g and ID cor to the maximum intensity of F2g and D bands, respectively, can roughly reflect the amount o defects (oxygen vacancies) in the obtained materials [72,74,75]. With appropriate tuning employed hydrothermal parameters, materials with high concentration of oxygen vacan obtained.…”

Copper-cerium mixed oxide catalysts have gained ground over the years in the field of heterogeneous catalysis and especially in CO oxidation reaction due to their remarkable performance. In this study, a series of highly active, atomically dispersed copper-ceria nanocatalysts were synthesized via appropriate tuning of a novel hydrothermal method. Various physicochemical techniques including electron paramagnetic resonance (EPR) spectroscopy, X-ray diffraction (XRD), N2 adsorption, scanning electron microscopy (SEM), Raman spectroscopy, and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS) were employed in the characterization of the synthesized materials, while all the catalysts were evaluated in the CO oxidation reaction. Moreover, discussion of the employed mechanism during hydrothermal route was provided. The observed catalytic activity in CO oxidation reaction was strongly dependent on the nanostructured morphology, oxygen vacancy concentration, and nature of atomically dispersed Cu2+ clusters.

“…[53,66,70] As it can be seen from Table 2, the effect of hydrothermal parameter is obvious in this case, too. 464, 600 and 1174 cm À 1 (I (600 + 1174) /I 464 ) can roughly reflect the amount of lattice defects (oxygen vacancies) in the obtained materials.…”

[53,66,70] As it can be seen from Table 2, the effect of hydrothermal parameter is obvious in this case, too. For example, the catalysts synthesized at 120°C and at higher concentrations of NaOH, possess higher concentration of defects, while the opposite trend is illustrated at 150°C and 180°C.…”

A series of highly active and selective CuCeO x catalysts was prepared via appropriate tuning of the parameters (concentration, temperature) of a citrates-hydrothermal method. The obtained catalysts were characterized by various physicochemical techniques such as (in-situ) X-ray diffraction (XRD), N 2 adsorption-desorption, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM), while preferential oxidation of CO (CO-PROX) in H 2 -rich stream was used as probe reaction. Suitable modification of the hydrothermal parameters resulted in catalysts with remarkable performance in CO-PROX reaction, which was strongly dependent on the concentration of oxygen vacancies and reduced copper species.
