“…Magnesium hydride has been favorable to be applied foreground in onboard hydrogen storage systems, due to its high gravimetric hydrogen storage capacity (7.6 wt%), natural abundance, and good reversibility. Unfortunately, pure MgH 2 shows slow sorption kinetics and high thermodynamic stability regarding the covered surface oxide layer and the low diffusion coefficient for H (Pistidda et al, 2014;Crivello et al, 2016;Yartys et al, 2019). In order to overcome these drawbacks of MgH 2 for practical applications, numerous studies attempted to enhance the hydrogen storage performance of MgH 2 , such by as alloying Mg with other elements to alter the thermodynamic stability, doping with additives or catalysts, and reducing Mg particles to nano scale.…”

In this work, Magnesium nanoparticles with Pd decoration, ranging from 40 to 70 nm, were successfully coprecipitated from tetrahydrofuran (THF) solution, assigned as the Mg-Pd nanocomposite. The Mg-Pd nanocomposite exhibits superior hydrogen storage properties. For the hydrogenated Mg-Pd nanocomposite at 150 • C, the onset dehydrogenation temperature is significantly reduced to 216.8 • C, with a lower apparent activation energy for dehydrogenation of 93.8 kJ/mol H 2 . High-content γ-MgH 2 formed during the hydrogenation process, along with PH 0.706 , contributes to the enhancing of desorption kinetics. The Mg-Pd nanocomposite can take up 3.0 wt% hydrogen in 2 h at a temperature as low as 50 • C. During lower hydrogenation temperatures, Pd can dissociate hydrogen and create a hydrogen diffusion pathway for the Mg nanoparticles, leading to the decrease of the hydrogenation apparent activation energy (44.3 kJ/mol H 2 ). In addition, the Mg-Pd alloy formed during the hydrogenation/dehydrogenation process can play an active role in the reversible metal hydride transformation, destabilizing the MgH 2 .

“…For instance, many LaNi 5 -based alloys have excellent hydrogen absorption kinetics and cyclability at near-ambient conditions, but can only store about 1.3 wt% hydrogen. MgH 2 contains 7.6 wt% hydrogen but is very stable and must be heated above 300 • C to release it [3,4]. The EU project HyCare (https://hycare-project.eu/) is currently developing a hydrogen storage tank based on TiFe-alloys with hydrogen capacities around 1.9 wt%.…”

Short-Range Structure of Ti0.63V0.27Fe0.10D1.73 from Neutron Total Scattering and Reverse Monte Carlo Modelling

et al. 2020

View full text Add to dashboard Cite

Ti-V-based body-centered cubic (BCC) alloys have potential for large-scale hydrogen storage if expensive vanadium is substituted with much cheaper Fe-containing ferrovanadium. Use of ferrovanadium reduces the alloys' hydrogen storage capacity. This is puzzling since the amount of Fe is low and hydrogen atoms are accommodated in interstitial sites which are partly coordinated by Fe in many intermetallic compounds. The present work is aimed at finding a structural explanation for Fe-induced capacity loss in Ti-V alloys. Since such alloys and their hydrides are highly disordered without long-range occupational order of the different metal species, it was necessary to employ a technique which is sensitive to local structure. Neutron total scattering coupled with reverse Monte Carlo modelling was thus employed to elucidate short-range atomic correlations in Ti 0.63 V 0.27 Fe 0.10 D 1.73 from the pair distribution function. It was found that Fe atoms form clusters and that the majority of the vacant interstitial sites are within these clusters. These clusters take the same face-centered cubic structure as the Ti-V matrix in the deuteride and thus they are not simply unreacted Fe which has a BCC structure. The presence of Fe clusters is confirmed by transmission electron microscopy. Density functional theory calculations indicate that the clustering is driven by thermodynamics.

“…many review articles have presented and discussed the possibility of designing Mg-based nanomaterials for hydrogen storage. [107][108][109] In 2017, a comprehensive review article published by Zhang et al presented the recent progress achieved to improve MgH 2 through catalytic agents and nanoconnement. 110 Mg and Mg 2 Ni were suggested 52 years ago as being suitable for use in internal combustion engines in the car industry.…”
