Advanced Materials and Technologies for Sustainability - part 2 Academic
In recent years, several studies highlighted that advanced nanomaterials have the potential to achieve a breakthrough in the development of novel technologies for a sustainable future. This session gathers contributions from the academic and industrial world related to materials for innovative CO 2 capturing and water treatment processes and novel CO 2 valorization techniques.
Membranes, as an applicative example, are fundamental elements for water purification and CO 2 separation plants, but their usage is also widespread in fuel cells, batteries and “blue energy” harvesting systems. Notwithstanding their large technological relevance, currently employed membranes suffer from many drawbacks and a further breakthrough in this field would require the use of innovative materials and in some cases complete membrane redesign. Several studies highlighted that nanomaterials have the potential to achieve a breakthrough in membranes performances, increasing membrane resistance (mechanical, thermal and chemical resistance) and lifetime, and enhance membrane selectivity.
Once captured CO 2 can be employed as valuable raw material to obtain value-added fuels and chemicals through photo/electrochemical reduction (CO2RR). The key challenge for this application is to develop highly selective, stable, efficient, environmental-friendly and inexpensive photo/electrocatalysts.
