Copper Oxide Unlocks Cryogenic Carbon Monoxide Oxidation

Researchers have discovered that the earth-abundant cuprous oxide (Cu₂O) can oxidize carbon monoxide (CO) into carbon dioxide (CO₂) at temperatures below 100 K. This finding provides a rare example of an earth-abundant metal oxide performing at cryogenic conditions, offering significant advancements for sustainable chemistry and catalysis.
