Intense human activity over the last decades resulted in growing environmental concerns, including alarming carbon dioxide (CO2) emission levels. CO2 is a major anthropogenic greenhouse gas which principally results from excessive combustion of fossil fuels. To reach the targets imposed by governments worldwide in the Paris Agreement (2015), but especially to fight climate change, we propose to focus on different aspects of CO2 capture and management, from the perspectives of materials science. The main purpose of this research is to identify materials and processes (physisorption/chemisorption mechanisms) to accomplish sustainable CO2 capture and sequestration. This means that we are not going to use energy for our processes, relying only on the materials chemistry.
