nanostructured ceo2 powders were synthesized via a series of hydrothermal and solution precipitation methods. three different hydrothermal methods including 1:2 and 1:1 bi:ce molar ratios at 180 °c for 48 h (s1 and s2, respectively) without calcinations and 2:1 bi:ce molar ratio at 180 °c for 48 h with calcinations (s3) were performed successfully for the synthesis of the target nanomaterials. ...
