Metal nanoparticle catalysts decorated with metal oxide clusters
Chemical Communications, 2012Au nanoparticles decorated with mononuclear Ti-oxo units dispersed in silica clusters were formed by activating Au nanoparticles (~2 nm) stabilized with Ti- and amine-functionalized siloxane oligomers. These Au nanoparticles were active catalysts for selective oxidation of propane to acetone, and the activity increased with increasing Ti density.

Enrofloxacin oxidative degradation facilitated by metal oxide nanoparticles
Chemosphere, 2012The activity of copper oxide, titanium carbide and silicon nitride nanoparticles for the oxidative degradation of environmentally relevant concentrations (μg L(-1) range) of enrofloxacin - an important veterinary antibiotic drug - in aqueous solutions was investigated. With hydrogen peroxide as an oxidative agent, both copper oxide and titanium carbide

Oxidation kinetics of metallic nanoparticles
Surface Science, 2003The performance of nanomaterials in specific applications can be greatly affected by a thin oxide layer on the surface. In this paper we put forward a model for the oxidation kinetics of metallic nanoparticles. For very thin oxide coatings on nanoparticles, it is necessary to take into account non-linear diffusion of the rate-determining ions.
