Stability of Colloidal Iron Oxide Nanoparticles on Titania and Silica Support.

ABSTRACT: Using model catalysts with well-defined particle sizes and morphologies to elucidate questions regarding catalytic activity and stability has gained more interest, particularly utilizing colloidally prepared metal(oxide) particles. Here, colloidally synthesized iron oxide nanoparticles (Fe _x O _y -NPs, size ∼7 nm) on either a titania (Fe _x O _y /TiO₂) or a silica (Fe _x O _y /SiO₂) support were studied. These model catalyst systems showed excellent activity in the Fischer-Tropsch to olefin (FTO) reaction at high pressure. However, the Fe _x O _y /TiO₂ catalyst deactivated more than the Fe _x O _y</
