Ethylene oligomerization under confinement using supported Cr( ii ) and Cr( iii ) catalysts

Key Points

• This research aims to understand how confining chromium active sites affects the selectivity in ethylene oligomerization.
• Utilized supported Cr(II) and Cr(III) catalysts
• Enclosed active sites within small mesopores
• Evaluated selectivity towards low molecular weight olefins (LAOs)
• Achieved selectivity for LAOs ≤ C12
• Suppressed polyethylene (PE) formation significantly
• Demonstrated effective tuning of oligomerization outcomes
