An edgy way to transform carbon dioxide

CO2 Reduction Plants are adept at turning CO2 into organic material. Unfortunately, humans have outpaced them in the other direction, releasing substantially more CO2 into the atmosphere than natural photosynthesis can concurrently consume. Although chemists are late entrants to the CO2 conversion game, they're now redoubling their effort in the face of climate change. Asadi et al. present a cost-effective catalyst for electrochemical reduction of CO2 to CO, an important feedstock for a wide range of commodity chemicals. The catalyst, molybdenum disulfide, is highly active at its edges and ultimately less expensive than the gold and silver previously investigated for this purpose. Nat.
