One-Pot Ethanol-Mediated Synthesis of Surface Si-Zoned ZSM-5 Zeolites

Key Points

• The research aims to improve the synthesis of zeolites that maintain stable catalytic properties by passivating external surface acid sites.
• Utilized a one-pot synthesis approach using ethanol as a medium.
• Focused on producing surface silicon-zoned ZSM-5 zeolites.
• Assessed the effectiveness of the synthesized zeolites in catalytic reactions.
• Demonstrated improved catalytic stability with the synthesized zeolites.
• Observed a reduction in non-shape-selective reactions in catalytic tests.
• Achieved a uniform distribution of silicon on the zeolite surface.
