Engineering Applications of Advanced Porous Materials
Abstract: The recent decade has witnessed the booming development of advanced porous materials (APMs) such as metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). Unlike their conventional counterparts (e.g., silica, activated carbon, zeolite), APMs have crystalline structures, uniform yet tunable pore size, and versatile chemical compositions suitable for various modifications. Born in the labs of synthetic chemists, APMs have become a frontier in material research with huge potentials in various applications including storage, separation, sensing, and catalysis. However, several engineering issues remain to be resolved before their large-scale utilization, such as stability, cost, and system integration.
In this talk, I will present our exploration into the engineering applications of APMs, with a focus on the development of water-stable zirconium MOFs as adsorbent materials for postcombustion CO2 capture. In addition, I will introduce our membrane studies for gas and water separation, emphasizing polycrystalline zirconium MOF membranes and ultrathin membranes containing two-dimensional MOF and COF nanosheets.
