        No reduction of CO occurs at 1 atm.  At 100 atm. reduction to CH₄ occurs, but a higher temperature (400°) is needed with a Mo than with a Ni catalyst.  Mo is activated by Mn, Cr, Th, and Cu but not by W.  Alkali destroys the activity.  Mo and Mo-Th catalysts for the hydrogenation of C₂H₄ are not poisoned by H₂S.
