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

(Waseda University) 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, for the first time in the world, scientists from Japan 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.
