Title: Ionic Liquid-based Materials for Advanced CO2 Separation Membranes
Speaker: Liliana C. Tomé
Affiliation: Isabel Marrucho Lab
Abstract:
The topic of global warming is one of the most important environmental issues that our world faces today. The adoption of 2016 Paris Protocol on the climate change makes the reduction of greenhouse gas emissions from industrial sources, through carbon dioxide (CO2) capture and re-use/storage, crucial. Considering that the energy input for materials regeneration and the capital cost of specific equipment are the most significantly contributors to the overall cost of the currently used CO2 capture process (gas absorption using amines), new cost-effective and high performance technologies urge to be researched, where the design of materials with the ability to efficiently separate CO2 from N2 is of vital importance.
Taking into account the extremely broad range of chemical and structural possibilities of ionic liquid (IL) chemistry, and the undeniable engineering and economical advantages of membrane technology, there has been growing interest in the exploitation of IL-based materials for CO2 separation membranes. The use of the structure–property relationship of ILs enables the molecular control of their remarkable CO2-affinity, while the use of IL-based supramolecular networks, like poly(ionic liquid)s (PILs), allows the introduction of structural material features relevant for gas separation.
In this communication, a perspective on different strategies that use IL-based materials as a unique tuneable platform to design task-specific advanced materials for CO2 separation membranes will be presented. The aim is not only to show the versatility of these materials in the development of innovative CO2 selective membranes but also point up their easy preparation. Based on the data obtained, the CO2 separation efficiency of different membranes will be discussed, as well as breakthroughs and key challenges in this field.
