Effect of LiOH treatment for LaNi5 on the accelerated H2 absorption under the mixture gas of CO2 was demonstrated. Presence of CO2 in H2 usually disturbs the H2 sorption reaction of LaNi5, however, an increased reaction rate was observed for the sample with LiOH pretreatment. Increasing amount of CO2 in H2, however, decreased the reaction rate drastically. For the sample of LaNi2.5Co2.5 the effect of LiOH was not confirmed.
