Abstract

The effect of CO₂on hydrogen absorption has been investigated for AB₂type alloys of Ti_0.515Zr_0.485Mn_1.2Cr_0.8(Ti-Zr-Mn-Cr) and Ti_0.515Zr_0.485Mn_1.2Cr_0.8M_0.1(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.
