Figure 2. A hybrid catalyst based on nickel anchored on nitrogen assembly carbon (Ni-NAC—see top middle image) and carbon nanowires (Cu-NWs—see bottom middle image) was produced that can convert carbon dioxide to carbon monoxide and then to ethylene (right image). In the top middle and bottom middle images, the light blue atoms represent atomically dispersed nickel, the blue atoms represent nitrogen and the red atoms are carbon. In the right image, the black atoms are carbon, the red atoms are oxygen and the white atoms are hydrogen. Figure courtesy of the Ames National Laboratory.
