“…As a result, it proves that rare-earth metals are insoluble in the TiFe phase. It is worth noting that the XRD peaks show that Mn and Co are not identified in the patterns, indicating that Mn and Co have replaced the Fe and solid solution in the TiFe phase, which is consistent with the conclusions of Qu [3].…”

“…After complete activation, cracks appear on the surface of the alloy, which increases the surface of the alloy by forming cracks and improves the kinetic performance. Moreover, the grain size of the as-cast alloys after PCT tests remains unchanged, which indicates that the pulverization of TiFe 0.86 Mn 0.07 Co 0.07 + x% Mm (x = 0,4,6,8) alloys can be controlled by adding Co, and this is consistent with the conclusions of Qu [3].…”

“…Leng et al [2] added Mn and Ce to the TiFe alloy, which greatly reduced the difficulty of alloy activation. Qu et al [3] added Mn and Co to the TiFe alloy. Their research showed that the addition of Co can greatly flatten the hydrogen absorption and desorption plateau and make the alloy easier to activate.…”

“…The focus of this work is to improve the performance of TiFe-based alloys in impure hydrogen gas, especially in the mixing of hydrogen and oxygen. The TiFe 0.86 Mn 0.07 Co 0.07 alloy [3] was used as the base alloy, which has excellent hydrogen absorption and desorption properties, and has been studied in our previous work. We hope that the addition of rare-earth elements (43% La, 56% Ce, 1% Pr, and Nd is easy to buy in the market, we call this metal mixture mischmetal) can improve the cyclic stability properties of the alloy and maintain its excellent hydrogen absorption and desorption properties.…”

The research aims to study the effect of adding mischmetal (Mm) to the TiFe0.86Mn0.07Co0.07 alloy on its hydrogen storage performance and cyclic stability. The results show that TiFe0.86Mn0.07Co0.07 + x% Mm (x = 0,4,6,8) alloys can be easily activated. The hydrogen absorption capacity of TiFe0.86Mn0.07Co0.07 + 4% Mm reaches 1.76 wt% (mass fraction) at 298 K. With the increase of Mm addition, the hydrogen storage capacity decreases slightly. Furthermore, after 40 absorption and desorption cycles in hydrogen containing 250 ppm O2, the alloy still has 36% of its initial hydrogen storage capacity, and the alloy can recover 93% of its hydrogen storage capacity through heat treatment.

“…Alloying and microstructure modification are the main approaches to improve the hydriding properties [10][11][12] . Shao et al reported that Mg-Co alloys present high hydrogen storage capacity of around 3 wt% [10] , which is obviously higher than that of TiFe 0.86 Mn 0.1-x Co x alloys (1.98 wt%) [13] . It was found that the hydrogenation kinetics and the H-storage capacity are dependent on the microstructure and phase composition of the alloys.…”

Magnesium alloys have a significant advantage, low density over other structure metals currently and have been widely used in various fields such as transportation and aerospace. With the development of research and the enlargement of research scope, more advantages have been developed: high storage capacity, high theoretical volumetric energy density, extraordinarily high damping capacity, good biocompatibility, excellent shielding efficiency as well as impressive thermal conductivity. Therefore Mg alloys have the potential to be various functional materials, such as hydrogen storage material, rechargeable electrochemical batteries, damping material, biodegradable implant material, electromagnetic shielding material, and thermal conductive material. Unfortunately, each kind of functional material has bottlenecks needing to be broken through, and a lot of researches have to be carried out. This review comprehensively covers the research progress and the up-to-date summary of Mg and Mg alloys as functional materials in recent years. The six kinds of functional materials above all will be discussed.

Catalysis in Solid Hydrogen Storage: Recent Advances, Challenges, and Perspectives

Catalysis is at the core of previous energy transition. It has enabled the use of oil and natural gas as our primary energy sources in unprecedented ways and led to feedstocks enabling exceptionally high living standards in human history. In a decarbonized economy with hydrogen as the new energy vector, catalysis is already playing a key role in producing hydrogen. However, catalysts for the effective storage of hydrogen must be advanced. Many solid hydrogen storage materials such as magnesium‐based hydrides, alanates, and/or borohydrides display promising hydrogen densities far superior to the current state of compressed or liquid hydrogen. These solid materials have thermodynamic and kinetic barriers which severely hinder their practical hydrogen uptake and release. To date, most of these barriers for solid hydrides (especially boron or nitrogen compounds) are modified via catalysis; however, the catalytic species per se and their roles are obscure. Herein, a comprehensive overview of various catalysts for solid hydrogen storage materials, their catalytic roles, and the underpinning mechanisms is provided. The current state of knowledge is critically reviewed and gaps where further research intensification is needed to support rapid hydrogen generation and storage in solid materials for the emerging hydrogen economy are identified.
