This analysis demonstrates enhanced olefin yields in zeolites with alkali metal doping, suggesting improved catalytic behavior and stability.

Alkali metal doping improves the structural stability of ZSM-5 zeolites, leading to better catalytic performance.
Li-exchanged ZSM-5 showed the best results, increasing catalyst lifetime by 5 hours compared to other modifications.
The modification shifted olefin products from acidic sites to alkali metal sites, reducing unwanted hydrogen transfer reactions.
Doping adjusted acid density and enhanced adsorption energy of light olefins, improving overall yield.

Dong et al. (2025) studied this question.
