Abstract :Direct 4-electron and single-electron transfer mechanisms are proposed for methanol decomposition. Kinetic models showed that the water-gas shift reaction was the rate determining step for both mechanisms at E = 0.392 V vs. RHE. Single-electron transfer is more likely to occur for methanol decomposition with a Tafel slope of 212.5 mV/dec, indicating that less than 1 electron transfer was the rate determining step for 0.3-0.6 V vs. RHE.
