Synthesis and characterization of hierarchically ordered macro–meso–microporous zeolite ZSM-5 (OMMM–ZSM-5)

Caption

(a) Schematic of the synthesis of hierarchically ordered macro–meso–microporous zeolite ZSM-5 (OMMM–ZSM-5) assembled by zeolite nanocrystals. (b)–(j) Characterizations of OMMM–ZSM-5(400), as a representative sample. (b)–(d) SEM images. (e) TEM image and ED pattern (inset). (f) TEM image of enlarged area outlined in (e). (g) HRTEM image of enlarged area outlined in (f). (h) SAXS and (i) WAXS pattern. (j) N2 adsorption–desorption isotherms and micropore-size, mesopore-size distribution (inset).
