Abstract

Abstract: The increasing demand on 1, 3-butadiene (BD) requires alternative production routes. Oxidative dehydrogenation (ODH) of 1-butene using CO2 as soft oxidant was systematically investigated over Pt-based catalysts. The effects of Pt chemical states, obtained on various supports and from different calcination environments, on the catalytic performance were studied. Different Pt 0 -PtO x particle sizes, having Pt 0 @PtO x core-shell structure observed from TEM images, were achieved by varying calcination environments. The BD selectivity was found to be structure sensitive and correlated with the Pt 0 -PtO x particle size.
