Catalytic performance at 950 °C. (a) C2,3 yield against the molar ratio of Na/Ca + Na in the chemical fabrication process. (b) C2,3 yield against the molar ratio of NaCl/Ca in the chemical fabrication process. The temperature dependence of the C2,3 yield is also shown in the inset of (b). Measurements were performed 20 min after reaching each temperature.
