Synthesis of Nanoceria with Varied Ratios of Ce³⁺/Ce⁴⁺ Utilizing Soluble Borate Glass.

ABSTRACT: Mixed-valence cerium oxide nanoparticles (nanoceria) have been investigated with pronounced interest due to a wide range of biomedical and industrial applications that arises from its remarkable redox catalytic properties. However, there is no understanding of how to control the formation of these two types of nanoceria to obtain Ce³⁺/Ce⁴⁺ ratios required in various applications. In this work, using a soluble borate glass, nanoceria with specific ratios of Ce³⁺/Ce⁴⁺ are created and extracted via controlled glass-melting parameters. Glass embedded with nanoceria as well as nanoceria extracted from the glass were studied via XANES and fitted with the Multivariate Curve Resolution (MCR) technique to calculate the ratio of Ce³⁺/Ce^4+</
