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 species in the amorphous silica phase. At higher loading additional aggregated forms of iron oxide exist. Isolated species in the silica matrix imply Brønsted acidity resulting in selective formation of ethylene, whereas clusters catalyze formation of ethylene and aldehyde
