Welcome to Prof. Hernández-Maldonado's Research Group Homepage!
The Nanoporous Sorbents and Adsorption Lab (NSSAL) at the University of Puerto Rico - Mayaguez focuses on the development and tailoring of new porous materials for chemical separation and recovery processes at ambient or mild conditions. The challenge is to synthesize 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 titaniumsilicates(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, just to mention a few.
