Approaches for the quantitative analysis of oxidation state in cerium oxide nanomaterials.

ABSTRACT: Cerium oxide nanomaterials (nanoceria, CNMs) are receiving increased attention from the research community due to their unique chemical properties, most prominent of which is their ability to alternate between the Ce³⁺ and Ce⁴⁺ oxidation states. While many analytical techniques and methods have been employed to characterize the amounts of Ce³⁺ and Ce⁴⁺ present (Ce³⁺/Ce⁴⁺ ratio) within nanoceria materials, to-date no studies have used multiple complementary analytical tools (orthogonal analysis) with technique-independent oxidation state controls for quantitative determinations of the Ce³⁺/Ce⁴⁺ ratio. Here, we describe the development of analytical methods measuring the oxidation states of nanoceria anal
