As the world's carbon dioxide emissions rise, increasing the threat of global warming, scientists are working on ways of capturing the gas produced by power plants, factories and vehicles. A group of scientists from L'Institut Lavoisier at the University of Versailles in France have developed a new nanotechnology material that has an astounding ability to absorb CO2.
Just one cubic metre of the material, chromium terephtalate or MIL-101 (Materiaux de L'Institut Lavoisier No. 101), can hold 400 cubic meters of CO2, double the amount of the nearest competing substance. The secret to its success: MIL-101 has a surface area of 6,000 square metres per gram and pores that are 3.5 nanometres in diameter, enabling it to capture and store great numbers of CO2 molecules. Ideally, MIL-101 will be used to make a filter that could capture CO2 as it is emitted.
