KAIST researchers developed a three-dimensional (3-D)
hierarchically porous nanostructured catalyst with carbon dioxide
(CO2) to carbon monoxide (CO) conversion rate up to 3.96 times
higher than that of conventional nanoporous gold catalysts. This
new catalyst helps overcome the existing limitations of the mass
transport that has been a major cause of decreases in the CO2
conversion rate, holding a strong promise for the large-scale and
cost-effective electrochemical conversion of CO2 into useful
chemicals.
