Reports: DNI552422-DNI5: Design of Zeolite Growth Modifiers: A Hierarchical Approach to Optimize Nanoporous Catalysts
Jeffrey D. Rimer, PhD, University of Houston
The
goal of this project is to develop rational approaches in zeolite synthesis to
selectively tailor material properties for improved performance in catalytic
applications. The specific objectives targeted for this period included the
following: (i) Systematic investigation of zeolite
growth modifiers (ZGMs) with varying site specificity for growing surfaces of
zeolite L (LTL type) crystals; (ii) Optimization of synthesis parameters as a
comprehensive method for tailoring zeolite crystallization in concert with the
design of effective ZGMs; and (iii) Developing novel analytical tools in
zeolite surface science capable of characterizing the effects of ZGMs on
surface growth.
This award has partially supported the research of one graduate student, one undergraduate student, and one postdoctoral researcher. The results of this period have resulted in two published manuscripts and a third that is currently in review. Moreover, graduate students and the PI have presented this work at conferences and invited seminars, including the American Chemical Society Meetings, the American Institute of Chemical Engineering Annual Meeting, and the North American Catalysis Society Meeting.
