Industry Applications: How Cerium Oxide CeO2 Powers Diverse Sectors
1. Glass Polishing
Cerium oxide polish is the gold standard for achieving flawless glass surfaces. Its nanoparticle structure enables efficient scratch removal without damaging optical clarity. Industries rely on CeO2 for polishing lenses, displays, and architectural glass.
2. Automotive Catalysts
In three-way catalysts, cerium cations facilitate oxidation of CO and NOx, reducing emissions. The oxygen storage capacity of doped ceria enhances catalytic performance in fuel cells and exhaust systems.
3. Semiconductor Manufacturing
Ceria-supported Pt particles are critical in CMP (chemical mechanical planarization) for silicon wafer finishing, ensuring atomically dispersed precision.
Unique Properties Driving Innovation: Why CeO₂ Is a Game-Changer
The crystal structure of cerium oxide features oxygen vacancies that enable rapid ionic conductivity, making it ideal for solid oxide electrolytes. Recent breakthroughs include single-atom catalysts like atomically dispersed Pt, which maximize active sites for dry reforming of methane.
Studies using density functional theory reveal how lattice oxygen mobility in CeO₂ enhances oxidation reactivity, pivotal for water-gas shift reactions.
Cerium Oxide CeO₂ in Scientific Research & Emerging Technologies
1. Nanotechnology & Biomedicine
Applications of cerium oxide nanoparticles span biomedical applications, including antioxidant activity for neutralizing free radicals.
2. Renewable Energy
Ceria’s role in photocatalytic hydrogen production is accelerating synthesis of clean fuels. X-ray photoelectron spectroscopy (XPS) confirms its efficacy in co oxidation.
3. Advanced Catalysis
Researchers at Department of Chemical Engineering leverage ceria-supported Pt particles to design surpassing the single-atom catalytic activity systems for heterogeneous catalysis.
