Hybrid copper-gold nanopartides convert CO2

摘要

Copper - the stuff of pennies and tea kettles - is also one of the few metals that can turn carbon dioxide (CO2) into hydrocarbon fuels with relatively little energy. When fashioned into an electrode and stimulated with voltage, copper acts as a strong catalyst, setting off an electrochemical reaction with CO2 that reduces the greenhouse gas to methane or methanol.
