OxidationO 0212 Partial Oxidations with NO2 Catalyzed by Large Gold Particles. — Gold in form

of very large particles (Au powder) and 16 nm carbon-supported nanoparticles is an active epoxidation catalyst when NO2 is used as the oxidant; under the same conditions O2 is ineffective. In contrast, both NO2 and O2 are effective for the Au-catalyzed oxy-dehydrogenation of secondary amines with the former being significantly more active. — (TURNER, M.; VAUGHAN, O. P. H.; LAMBERT*, R.
