Figure 6. Complete hydrogen absorption-desorption PCT curves of (A) HEA-1, (B) HEA-2, (C) HEA-3, (D) HEA-4, (E) HEA-5, (F) HEA-6, (G) HEA-7, and (H) HEA-8 at different temperatures, together with (I) the Van’t Hoff fitting results obtained from the hydrogen absorption plateau pressures. HEA: High-entropy alloy; PCT: pressure-composition isotherm.
