Synthesis Of Large Crystal Transition Metal Substituted Zeolite Zsm-5, Tara L. Schaeffer, Scott Kirkby
Synthesis Of Large Crystal Transition Metal Substituted Zeolite Zsm-5, Tara L. Schaeffer, Scott Kirkby
Scott J. Kirkby
Crystals of ZSM-5 containing Cu, Mn, and Fe have been synthesized up to 85 μm in length along the long axis.
This is 1 to 2 orders of magnitude larger than any previously reported. Phase identification was accomplished by powder XRD. A modified Charnel’s method was used to chelate the transition metal and the aluminum in the synthesis gel. Element alanalysis was performed by ICP-AES, confirming the presence of the metals. The metals are resistant to leaching under ion exchange and, as determined by partial dissolution, incorporated throughout the volume of the crystals.
