Simultaneously Improving the Selectivity and Stability of HZSM-5 Zeolite by NaOH Treatment in Aqueous Ethanol-to-Propylene Reactions

Mesoporous nanoscale HZSM-5 zeolites were prepared by alkali treatment and characterized by XRD, SEM, NMR, ICP-OES, N2 adsorption/desorption, NH3-TPD, Py-IR, and TG techniques. The effects of NaOH concentration on pore structure, acidity, and catalytic performance of nanoscale HZ...
