A comparison of TiF₃ and NbF₅ catalytic effects on hydrogen absorption and desorption kinetics of a ball-milled Mg₈₅Zn₅Ni₁₀ alloy

Abstract

TiF3 shows better catalytic influence on hydrogen storage property of Mg85Zn5Ni10 than NbF5.

A catalytic mechanism investigation of TiF3 on hydriding/dehydriding properties of Mg85Cu5Ni10 alloy

“…Our previous study has conrmed that these cracks contribute to accelerating the rate of hydrogen absorption and desorption. 12,27 In addition, it is worth noting that…”

“…Nevertheless, there are still some important technical problems for the hydrogen energy system to fully implement and replace fossil fuels. [10][11][12][13][14][15][16][17] The rst is cheap and massproduced hydrogen production technology. The second is hydrogen storage and transportation.…”

“…In addition, our study has proved that TiF 3 significantly improved the kinetics of hydrogen absorption and desorption of Mg 85 Zn 5 Ni 10 alloy, and reduced the dehydrogenation activation energy to 75.514 kJ mol −1 . 12 Therefore, we choose TiF 3 as catalyst to study the catalytic effect on the hydrogen storage properties of Mg–Cu–Ni alloy.…”

Using Ball Milling for Modification of the Hydrogenation/Dehydrogenation Process in Magnesium-Based Hydrogen Storage Materials: An Overview

“…Many metal halides have a good catalytic effect on the hydrogen desorption temperature and hydrogen absorption kinetics of magnesium-based hydrogen storage materials [123][124][125][126][127][128]. Jin et al [129,130] investigated the effect of transition metal fluorides on the hydrogen absorption/desorption properties of MgH 2 .…”

Microstructure and hydrogen storage kinetics of Mg89RE11 (RE = Pr, Nd, Sm) binary alloys

“…The results shows that the hydrogen sorption properties of Mg-based alloys can be substantially improved by forming composites having catalytic effect and proper microstructure features. [47][48][49]…”
