Optical properties of nanocrystalline ceria
Applied Optics, 1997We believe that, for the first time, the UV-visible optical reflectivity of nanocrystalline ceria with various particle sizes has been measured, and their optical absorption characteristics have been studied by Kramers-Kronig transformation. The wide absorption band in the 200-480-nm range consisted of two narrow bands. This wide band was designated as

Steam reforming of methanol over ceria and gold-ceria nanoshapes
Applied Catalysis B: Environmental, 2010In this work we have found that a small amount (∼1 at.%) of gold deposited on ceria nanorods exhibits excellent catalytic activity for the low-temperature steam reforming of methanol (SRM). Gold clusters (

Engineering the Bioactivity of Flame-Made Ceria and Ceria/Bioglass Hybrid Nanoparticles
ACS Applied Materials & Interfaces, 2018Despite its use as a highly efficient and reusable catalyst in research and industrial settings, cerium oxide nanoparticles or nanoceria have yet to gain a foothold in the biomedical field. A variety of beneficial effects of nanoceria have been demonstrated, including its use as an inorganic nanoenzyme to mimic antioxidant enzymes, to protect mammalian

Reactivity of ceria, Gd- and Nb-doped ceria to methane
Applied Catalysis B: Environmental, 2002Abstract The reactivity of methane with ceria, and ceria doped with either 10 cation% Gd, 1.4 cation% Nb, 5 cation% Nb has been investigated using temperature-programmed reaction (TPRx) and isothermal reaction at 900 °C in 5% methane in argon. The influence of the calcination atmosphere on the Nb-doped ceria has also been studied.
