We use the last elementary steps as examples to understand the information contained in is thermodynamically more favored than CHO * , since i13 is brighter than i8, and thus, methanol generation is more prone to evolve through the i8 route. All these observations are in line with previous computational and experimental works . . The magnitude of the energy barriers for each elementary step is represented by the color and the thickness of the arrows, while the color of the nodes represent the stability of the intermediates. Bright colors imply unstable intermediates or high activation energies.
