Abstract

The iron location in FeSBA-15 strongly influences the selectivity to dehydrogenation and dehydration in ethanol conversion. At low iron loading, Fe is present as isolated Fe³⁺ species in the amorphous silica phase. At higher loading additional aggregated forms of iron oxide exist. Isolated Fe³⁺ species in the silica matrix imply Brønsted acidity resulting in selective formation of ethylene, whereas FeO_x clusters catalyze formation of ethylene and aldehyde.
