Performance Evaluation of Materials for the Capture and Removal of Pollutant Gases (NO₂, CO₂, SO₂)

M. Zbair, J.Brendlé, S.Hajjar-Garreau, L.Dzene

This research is part of broader efforts to combat air pollution and manage greenhouse gas emissions. The primary objective is to design advanced materials capable of capturing harmful gases such as nitrogen dioxide (NO₂), carbon dioxide (CO₂), and sulfur dioxide (SO₂). Addressing both environmental and industrial challenges, the work aims to provide innovative and sustainable solutions to reduce pollutant emissions and mitigate their impact on climate change.
A key tool used in this research is breakthrough curve analysis, which allows for the dynamic evaluation of material performance. This method provides insight into adsorption capacity, kinetics, and saturation behavior under flow conditions, enabling a quantitative understanding of gas-material interactions and helping to optimize gas capture processes.
This research contributes to energy transition efforts and strengthens IS2M’s expertise in the development of advanced materials for atmospheric pollution control.
Main Research Areas :
1. Dynamic Adsorption and Reduction of NO₂ : Investigation of reduction kinetics and optimization of catalytic materials for converting NO₂ into NO.
2. Capture of CO₂ and SO₂ : Development of tailored porous materials for the selective capture and storage of these gases.
