The sample prepared by impregnation method has the lowest reducibility, and the sample prepared by sol-gel method shows the highest reducibility.
During the deposition of 4 wt % Rh onto a ceria-alumina support (method I), the cerium seems to be partially reduced, resulting in a similar Ce3+/Ce4+ ratio to the sample prepared by using method II (ceria on Rh/Al2O3).
As a comparison, the sample prepared by sol gel method is also discussed.
As a result, the recombination of the photogenerated carriers is greatly suppressed on the sample prepared by our method.
To study, the influence of synthesis methodology, NiAl3-HT was also synthesized through urea and hexamine hydrolysis wherein sample prepared by former method offered maximum crystallinity among all samples synthesized.
The d-spacing value has been calculated to be 0.31 nm (Figure 5c), identical to the theoretical value of 0.31 nm for (112) planes of kesterite CZTS. Figure 5 SEM, TEM, and HRTEM images and SAED pattern of the CZTS sample prepared by hydrothermal method.
Among all the deposition methods studied, the sample prepared by the CV method possesses superior photoelectrical properties and photocatalytic activity.
Similarly, to assess the influence of the sample preparation on the gene expression profile, we compared the HepG2 transcriptomes obtained from the same physical sample prepared using two protocols: method M (dataset HR_m) and method C (dataset HR_c).
The reason that total RNA samples prepared using method B demonstrate poor quality is probably due to the fact that impurities such as salts or residual amounts of phenol or ethanol are carried over in the sample preparation assay and subsequently impair enzymatic reactions.
Thus, the sample prepared via co-precipitation method and the solid ceramic sintered through microwave can be a promising electrolyte for fuel cells operated at intermediate temperature.
