Abstract
This 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.
