Capturing carbon with copper

A team of researchers in the Netherlands have devised a trap that can pull carbon dioxide out of the air.  

The researchers, led by Elisabeth Bouwman at the Leiden Institute of Chemistry at Leiden University, have developed a selective copper complex - predisposed to capture CO₂ and ignore other atmospheric gasses. Equally important, the trapped CO₂ can be removed through electrochemistry, requiring a relatively low electrical potential to replace lost electrons.  More...
