“…At present, the performance of the ZrCo-based alloy cannot meet requirements, and it is unable to meet the high-pressure transportation required by the storage and delivery system at the current working temperature that suppresses disproportionation, or eliminate the disproportionation at the high temperature that meets the storage and transport rate. Obviously, element substitution is the most tried and promising way to improve the anti-disproportionation of the ZrCo alloy, compared to other methods [ 64 , 67 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 ]. To date, many experiments have shown that samples with smaller lattice parameters and cell volume have the expected anti-disproportionation ability.…”

Hydrogen-induced disproportionation (HID) during the cycles of absorption and desorption leads to a serious decline in the storage capacity of the ZrCo alloy, which has been recognized as the biggest obstacle to its application. Therefore, the prerequisite of a ZrCo application is to solve its anti-disproportionation problem in the field of rapid hydrogen isotope storage. Beyond surface modification and nanoball milling, this work systematically reviews the method of element substitution, which can obviously improve the anti-disproportionation. From a micro angle, as hydrogen atoms that occupy the 8e site in the ZrCoH3 lattice are instable and are considered to be the driving force of disproportionation, researchers believe that element substitution by changing the occupation of hydrogen atoms at the 8e site can improve the anti-disproportionation of the alloy. At present, Ti/Nb substitutions for the Zr terminal among substitute elements have an excellent anti-disproportionation performance. In this work, up-to-date research studies on anti-disproportionation and its disproportionation mechanism of the ZrCo alloy are introduced by combining experiments and simulations. Moreover, the optimization of the alloy based on the occupation mechanism of 8e sites is expected to improve the anti-disproportionation of the ZrCo alloy.

“…Conic ´et al 26 studied the effect of Ta doped ZrCo, which has an important influence on the surface reactivity. Wang et al 27,28 found that ZrCo coated with catalytic nanocrystals Ni and Pd can significantly improve the hydrogen absorption kinetic properties, due to their molecular hydrogen dissociation properties. Furthermore, theoretical calculations have been utilized to explore the nature of hydrogen interaction with metal surfaces, which is not capable of being grasped by experimental techniques.…”

“…hydrides and combinations of different hydrogenating metals (such as Pd and V [5], Pd and ZrCo alloys [6], Pd and Ag [7] ) have proved to be a promising class of materials for hydrogen storage, since storing hydrogen in the solid form addresses the safety concerns linked to liquid or gaseous hydrogen [8,9]. Palladium is especially well-known for its catalytic activity towards hydrogen dissociation and for its ability to absorb large quantities of hydrogen, leading to the formation of αand β-phase hydrides [10][11][12][13].…”

We investigated the structural evolution of electrochemically fabricated Pd nanowires in situ by means of grazing-incidence transmission small- and wide-angle x-ray scattering (GTSAXS and GTWAXS), x-ray fluorescence (XRF) and two-dimensional surface optical reflectance (2D-SOR). This shows how electrodeposition and the hydrogen evolution reaction (HER) compete and interact during Pd electrodepositon. During the bottom-up growth of the nanowires, we show that β-phase Pd hydride is formed. Suspending the electrodeposition then leads to a phase transition from β-phase Pd hydride to α-phase Pd. Additionally, we find that grain coalescence later hinders the incorporation of hydrogen in the Pd unit cell. GTSAXS and 2D-SOR provide complementary information on the volume fraction of the pores occupied by Pd, while XRF was used to monitor the amount of Pd electrodeposited.
