The effect of CO2on hydrogen absorption has been investigated for AB2type alloys of Ti0.515Zr0.485Mn1.2Cr0.8(Ti-Zr-Mn-Cr) and Ti0.515Zr0.485Mn1.2Cr0.8M0.1(Ti-Zr-Mn-Cr-M, M = Fe, Co, or Ni) in order to develop metal hydrides for a hydrogen purification and storage system. A magnitude of CO2poisoning tolerance was evaluated by comparing hydrogen absorption properties before and after CO2exposure. As the results, an order of CO2tolerance was Ti-Zr-Mn-Cr-Ni < Ti-Zr-Mn-Cr < Ti-Zr-Mn-Cr-Co < Ti-Zr-Mn-Cr-Fe. It suggests that the AB2alloys have dependence of additive 3d-transition elements on CO2tolerance. Ti-Zr-Mn-Cr-Fe has the highest CO2tolerance among them. The additive of Fe and Co improves tolerance of CO2poisoning for hydrogen absorption properties. On the other hand, Ni element in AB2alloy decreases CO2tolerance. The estimated enthalpy change between CO2and the alloys surface was comparable to the formation of metal oxide. And the CO2-exposed AB2alloys after reacting with hydrogen desorbed methane gas. Therefore, CO2would dissociate to CO and O on the surface of alloys, and then oxygen atom reacts with the alloys.
