Copper-indium oxide: A faster and cooler way to reduce our carbon footprint

Emergent e-fuel technologies often employ the reverse water-gas shift (RWGS) reaction to convert atmospheric CO2 to CO. While efficient, this reaction requires high temperatures and complex gas separation for high performance. However scientists have now demonstrated record-high CO2 conversion rates at relatively low temperatures in a modified chemical-looping version of RWGS using a novel copper-indium oxide.
