NSSAL’s work on the development of carbon/MOF hierarchical composites for the removal of contaminants of emerging concern from water has been highlighted in ACS Chemistry of Materials’ Virtual Issue on Multifunctional Nanoporous Materials in Latin America
The Nanoporous Sorbents and Adsorption Lab (NSSAL) at the University of Puerto Rico – Mayaguez focuses on developing and tailoring new porous materials for chemical separation and recovery processes at ambient or mild conditions. The challenge is synthesizing new materials with specific framework topologies and novel compositions based on templated hydrothermal paths or surface functionalization.
Our synthesis efforts include metal-substituted aluminophosphates (MAPOs), flexible titanosilicates(TS), mesoporous silica, coordination polymers, and metal-organic frameworks (MOFs). In terms of applications, we are interested in carbon dioxide removal in closed systems, ultrapurification of light gas mixtures, and removal of emerging organic contaminants from potable water sources, to mention a few.
