Herein, we report that the TiFe0.92Mn0.04Co0.04 catalyst can overcome the abovementioned challenges. The synthesized MgH2-30 wt% TiFe0.92Mn0.04Co0.04 can release 4.5 wt% of hydrogen in 16 min at 250 °C, three times as fast as MgH2. The activation energy of dehydrogenation was as low as 84.6 kJ mol−1, which is 46.8% reduced from pure MgH2. No clear degradation of reaction rates and hydrogen storage capacity was observed for at least 30 cycles. Structural studies reveal that TiFe0.92Mn0.04Co0.04 partially decomposes to in-situ generated α-Fe particles dispersed on TiFe0.92Mn0.04Co0.04. The presence of α-Fe reduces the formation of an oxide layer on TiFe0.92Mn0.04Co0.04, enabling the activation processes. At the same time, the hydrogen incorporation capabilities of TiFe0.92Mn0.04Co0.04 can provide more hydrogen diffusion paths, which promote hydrogen dissociation and diffusion. These discoveries demonstrate the advanced nature and importance of combining the in-situ generated α-Fe with TiFe0.92Mn0.04Co0.04.

Commonly used HSAs in the hydrogen isotopes field are Zr2M (M = Co, Ni, Fe) alloys, metallic Pd, depleted U, and ZrCo alloy. Specifically, Zr2M (M = Co, Ni, Fe) alloys are considered promising tritium-getter materials, and metallic Pd is utilized to separate and purify hydrogen isotopes. Furthermore, depleted U and ZrCo alloy are well suited for storing and delivering hydrogen isotopes. Notably, all the aforementioned HSAs need to modulate their hydrogen storage properties for complex operating conditions. In this review, we present a comprehensive overview of the reported modification methods applied to the above alloys. Alloying is an effective amelioration method that mainly modulates the properties of HSAs by altering their local geometrical/electronic structures. Besides, microstructural modifications such as nano-sizing and nanopores have been used to increase the specific surface area and active sites of metallic Pd and ZrCo alloys for enhancing de-/hydrogenation kinetics. The combination of metallic Pd with support materials can significantly reduce the cost and enhance the pulverization resistance.
