New materials can selectively capture CO2, scientists say

Scientists have created metal-organic crystals capable of soaking up carbon dioxide gas like a sponge, which could be used to keep industrial emissions of the gas out of the atmosphere.

Chemists at the University of California Los Angeles said the crystals — which go by the name zeolitic imidazolate frameworks, or ZIFs — can be tailored to absorb and trap specific molecules.

“Now we have structures that can be tailored precisely to capture carbon dioxide and store it like a reservoir, as we have demonstrated. No carbon dioxide escapes. Nothing escapes — unless you want it to do so. We believe this to be a turning point in capturing carbon dioxide before it reaches the atmosphere.”
