Dr Dan Zhao from NUS (Singapore) will give a lecture tomorrow at 10 am (amphi Joliot, ESPCI) dealing with the use of Metal Organic Frameworks or Covalent Organic Frameworks Nanosheets to prepare thin membranes for the capture of CO2 under post-combustion conditions.

Abstract

The recent decade has witnessed the booming development of advanced porous materials (APMs) such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), etc. 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, catalysis, etc. 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 in the engineering applications of APMs, with a focus on the development of water-stable Zr MOFs as adsorbent materials for postcombustion CO2 capture. In addition, I will introduce our membrane studies for gas separation and water purification, emphasizing polycrystalline Zr MOF membranes and ultrathin membranes containing two-dimensional MOF and COF nanosheets.
