Copper-infused breakthrough converts CO2 into ethylene Copper-infused breakthrough converts CO2 into ethylene

Amid the quest to reduce reliance on fossil fuels, a groundbreaking innovation has emerged. A research team has harnessed the power of green electricity to transform carbon dioxide into ethylene. The innovation centers around an alkali-metal electrolyte and uses pure water as a metal-free anolyte to prevent carbonate formation and salt deposition. Referring to their design as the APMA system, the group has integrated an anion-exchange membrane (AEM) denoted by A, a proton-exchange membrane (PEM) signified by P, and the resulting membrane assembly designated as MA. The resulting alkali-metal-free cell stack, containing the APMA and a copper electrocatalyst, has achieved
