Abstract
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 1H spin-lattice relaxation have been treated within an exchange model.
Research highlights▶ Proton NMR provides information on hydrogen mobility in metal hydrides. ▶ In Ti-V-Cr the relaxation rates strongly depend on the vanadium fraction. ▶ The activation processes start earlier for the vanadium reach hydrides. ▶ Addition of Zr-Ni or Hf-Ni alloys enhances the hydrogen mobility in Ti-V-Cr.
