Water increases Fischer Tropsch synthesis (FTS) rates on Ru through H-shuttling processes. Chemisorbed hydrogen (H) transfers its electron to the metal and protonates the O-atom of CO to form COH, which subsequently hydrogenates to *HCOH* in the kinetically relevant step. H 2O also increases the chain length of FTS products by mediating the H-transfer steps during reactions of alkyl groups with CO* to form longer-chain alkylidynes and OH*.
