New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2

New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2 In a quest to find a way to convert carbon dioxide into something useful, researchers from Oak Ridge National Labs in TN stumbled across an inexpensive, room-temperature catalyst for turning CO2 into ethanol.The new catalyst is made of copper nanoparticles, electroplated onto a substrate of vapor-deposited, nitrogen-doped graphene nanospikes, all atop a slice of n-type silicon semiconductor.

Nanocubes of this metal can generate fuel from CO2 using only sunlight

Nanocubes of this metal can generate fuel from CO2 using only sunlight Researchers from Duke University have discovered a way to use nanocubes of rhodium as a cheap solar-powered catalyst, converting carbon dioxide into methane quickly and with high efficiency.But what actually makes rhodium nanocubes special is that using them makes the reaction tunable.
