After increasing the input C/O ratio to 1.0, a similar story emerges (Figure ). The peak of the volcano plot (the hot spot in the heat map) does not move significantly for CH 4 conversion or synthesis gas yield, but moves towards more weakly binding metals for the full oxidation yield (the bright zone moves up and right from Figure to 7f). This is mostly due to the reaction CO⇤ + O⇤ * ) CO 2 + 2 ⇤ being faster in the CMPO-BMA models.
