Abstract
This study introduces a novel synthesis apparatus for Copper Benzene-1,3,5-tricarboxylate (Cu-BTC) within the HKUST-1 framework, introducing a new technology to grow larger crystals. Metal-Organic Frameworks (MOFs) like Cu-BTC exhibit remarkable properties, including high surface area and tunable pore sizes, making them promising candidates for applications in efficient gas separation, specifically carbon capture. Existing growth mechanisms are confined to producing millimeter-scale crystals characterized by defects and undesirable agglomerations. These defects often exhibit reduced performance and stability, limiting their efficacy in critical applications. To address this challenge, we propose an innovative synthesis apparatus featuring a corrosion-compatible autoclave designed to withstand the acids essential for Cu-BTC growth, providing a controlled environment for precise pressure and temperature adjustments. Our apparatus will conduct solvothermal growth to achieve centimeter-scale crystals with improved purity and uniformity. By overcoming current limitations in synthesis, our work will enable more accurate characterization of MOF properties and facilitate their application in various fields. Future research will optimize the synthesis process, explore alternative growth conditions, and demonstrate practical applications. By continuing to push the boundaries of MOF synthesis, we aim to integrate Cu-BTC into gas capture devices, driving meaningful progress toward a more sustainable future.
About Itzel Esparza
Itzel Esparza is a senior at Lehigh University pursuing a B.S. in Materials Science and Engineering with a minor in Spanish Language and Hispanic Cultures. She is currently serving as the Vice President of the Lehigh Spanish Club and previously served as the undergraduate representative of the MSE Diversity, Equity, and Inclusion committee.
Itzel has been conducting research with Dr. Siddha Pimputkar for the past year. Her research endeavors have been diverse, from developing a Python plotting program for XRD data visualization to focusing on designing a growth apparatus for a copper-based metal-organic framework (Cu-BTC). Additionally, she is involved in integrating a high-pressure tube furnace for a study aimed at understanding the corrosion behavior of various stainless steels in an ammonia-rich environment.
Following graduation, Itzel plans to continue her academic journey at Lehigh University, where she will pursue her Ph.D. under the guidance of Dr. Siddha Pimputkar.
