CO2 photocatalysis sees the light of day

Recently, Dimensional Energy, a spin-off company from Cornell University, has designed, built, and tested, a pilot-scale photoreactor for making chemicals using just carbon dioxide and sunlight, no additional heating or electricity is needed. As shown in the photograph, the setup consists of a tracking system, which collects and concentrates sunlight to the wave-guide reactor where the CO2 is catalytically converted to carbon monoxide or methanol by a In2O3-xOHy catalyst. This pilot reactor is now tested at a CO2 emitting coal-fired power-plant located at Gillette, Wyoming, USA to compete for the prestigious Carbon XPrize, a step closer to the vision of the solar fuel refinery.
