New material captures twice as much CO2
PNNL's team has created a new series of materials based on metal-organic frameworks (MOFs), that has tiny "cages"—trapping CO2 before it reaches the atmosphere. The cages themselves consist of metal ions linked together with organic ligands forming a porous network that trap gas molecules. The team combined "off the shelf" chemicals—zinc nitrate and organic building blocks that serve as the foundation for the new materials. The unique molecules have two to three times the capacity for carbon dioxide uptake as conventional solvents, and appears to have an extremely high preference for carbon dioxide over other gases. The team did comprehensive testing using the U.S. Department of Energy's Environmental Molecular Sciences Laboratory (EMSL), to determine size and shape of the crystal.

One of the most significant problems in the carbon capture and storage (CCS) industry is how to separate harmful greenhouse gases (GHG) before those GHGs are distributed to the atmosphere.

SAMMS™—Self-Assembled Monolayers on Mesoporous Supports®—is an award-winning technology with broad applications in the remediation, water treatment, catalyst, sensor and controlled-release markets. SAMMS are created by attaching a monolayer of molecules to mesoporous ceramic supports.

Heavy metal contamination of our environment is a daunting challenge facing the world today, from groundwater, to surface water, to the air that we breathe. Prevention, or remediation, of heavy metal pollution is therefore a key component of "green" manufacturing, technology sustainability and responsible environmental stewardship.
