Thin layers of cerium dioxide (Ce[O.sub.2]) have been prepared by various methods such as electrodeposition [7-9], hydrothermal [10], ion beam-assisted deposition [11], laser chemical vapor deposition [12-14], microwave-assisted heating [15], precipitation [16,17], magnetron sputtering [18,19], and sol-gel [20] methods.
The 0.5 h electrodeposition at the highest concentration is suitable for preparation of thicker layers of cerium dioxide.
Typical particle sizes of as-prepared and calcined cerium dioxide samples shown in the corresponding SEM data were 4 and 7 nm, respectively, regardless of their concentrations, indicating that nucleation was driven mainly by the applied potential.
