Nanomaterials as catalysts for CO transformation into value-added products: A review.

Carbon dioxide (CO is the most important greenhouse gas (GHG), accounting for 76% of all GHG emissions. The atmospheric CO concentration has increased from 280 ppm in the pre-industrial era to about 418 ppm, and is projected to reach 570 ppm by the end of the 21 century. In addition to reducing CO emissions from anthropogenic activities, strategies to adequately address climate change must include CO capture.
