The danger posed by rising levels of atmospheric carbon dioxide has seen many schemes proposed to remove a proportion it from the air. Rather than simply capture this greenhouse gas and bury it in the ground, though, many experiments have managed to transform CO2 into useful things like carbon nanofibers or even fuels, such as diesel. Unfortunately, the over-arching problem with many of these conversions is the particularly high operating temperatures that require almost counterproductive amounts of energy to produce relatively low yields of fuel. Now researchers at the University of Southern California (USC) claim to have devised a way to take CO2 directly from the air and convert it into methanol using much lower temperatures and in a correspondingly simpler way.
