Nanospikes Convert Carbon Dioxide Back Into Ethanol

A new chemical process turns carbon dioxide into ethanol using commonly-found catalysts and electricity. In a sense, they’ve figured out a way to put the genie back in the bottle.

The alchemic process of converting greenhouse gases into usable energy is an appealing means of both addressing climate change and providing sustainable sources of energy. Converting carbon dioxide into energy and other useful products has been done before, but the process isn’t efficient or cheap enough to impl
