Abstract
The UCF invention introduces a novel class of bi-metallic rare earth oxide nanomaterials designed for enhanced catalytic and biomedical applications. These materials combine lanthanide oxides with transition metals to create nanoparticles with mixed valence states and high oxygen vacancy densities. Imagine a single nanoparticle acting as a miniature chemical reactor, accelerating redox reactions and generating reactive oxygen species for disinfection and therapy. The unique surface chemistry and multi-metal clustering enable superior performance in catalysis, environmental remediation, and medical treatments/
Technical Details: The nanomaterials consist of RxOyM1M2 clusters, where R is a lanthanide (e.g., Ce), and M1/M2 are transition metals or their oxides (e.g., Zn, Ag). Synthesized via aqueous hydrolysis and aging, the nanoparticles exhibit spherical morphology with sizes ranging from 5–100 nm. Surface phases contain mixed valence states (e.g., Ce3+/Ce4+, Zn0/Zn2+, Ag0), contributing to high oxygen mobility and catalytic activity. The composition and properties are tunable through metal ratios and synthesis conditions.
