Synthesis and Characterization of Nd-Doped ZSM-5 Zeolite from Diatom Mud

Abstract:

ZSM-5 zeolite was synthesized using diatom mud as the raw material, and then doped with different amounts of Nd₂O₃. Nd/ ZSM-5 zeolite was synthesized at °C for 24 h after stirring at high speed and aging in the synthesis mixture with the molar composition of 1.5 Nd₂O₃:25Na₂O:150SiO₂:1Al₂O₃:10TPABr:2500H₂O.XRD confirmed Nd/ZSM-5 crystal phase. TEM showed that Nd/ZSM-5 zeolite crystal sizes are about 2-4μm. EDS shows Nd/ ZSM-5 zeolites chemical element compound. FT-IR analysis further showed that they are pentacyclic with typical absorption summit of ZSM-5 at about 547 cm^-1.
