Mechanism of Cs Precursor Effect on Cs-Ag/Al 2 O 3 : Tuning Oxygen Activation for Ethylene Epoxidation

Key Points

• The research aims to explore how various cesium (Cs) precursors affect the activation of oxygen and thereby improve the production of ethylene oxide during ethylene epoxidation.
• Analyzed the impact of multiple Cs precursors on the catalytic properties.
• Investigated geometric and chemical changes induced by different precursors.
• Conducted experiments to measure ethylene oxide production rates.
• Different Cs precursors significantly altered the geometric structure of the catalyst.
• Effective oxygen activation was linked to higher production rates of ethylene oxide.
• The findings suggest that optimizing Cs precursor selection can enhance catalytic performance.
