Date: jun-15. 2020.
Doi: 10.1016/j.micromeso.2020.110149.

Abstract:
Ferrierite zeolite was synthesized by a co-structure-directing route using a highly flexible diquaternary ammonium cation (N,N’-bis-triethylpentanediyldiammonium) as a structure directing agent in combination with tetramethylammonium as a small co-structure-directing agent. Strong alterations of the C-13 NMR bands of the bulky organic [leer más]
