NMR study of metal-hydrogen systems for hydrogen storage
Résumé
In this contribution we report on the results of our recent 1H NMR studies of different metal hydrides of interest for reversible hydrogen storage applications: Ti-V-Cr alloys of various compositions, pure and with Zr7Ni10 or Hf7Ni10 additives, and in additives themselves. The temperature dependences of 1 H spin-lattice relaxation have been treated within an exchange model.
