Abstract

A combination of spectroscopic and catalytic investigations led to the surprising conclusion that not isolated WVI species but WO3 oxide is the most active and stable phase for olefin epoxidation with H2O2. Optimal activity was subsequently found for a nanoparticulate WO3 prepared by flame aerosol technology. This material is characterized by a 50% increase in activity per WVI site, and a 35-fold increase in space time yield, compared with the current benchmark catalyst.
