This study shows that low-temperature light-off can be achieved in CO/C3H6 mixtures with suitable choice of aging, pre-treatment, and evaluation conditions on Pd/Stab_CZO model catalysts. A sequence of light-off reaction steps on Pd/Stab_CZO that circumvents the strong inhibition associated with propylene adsorption is proposed.
