Excessive use of fossil fuels leads to undesired carbon dioxide (CO2) generation, accelerating climate change. One way to tackle this is by converting CO2 into value-added chemicals. On this front, researchers have recently utilized a novel redox couple, for the purpose.Excessive use of fossil fuels leads to undesired carbon dioxide (CO2) generation, accelerating climate change.
