Interstitiaalihydriditbased

Interstitiaalihydriditbased refers to materials where hydrogen atoms occupy interstitial sites within the crystal lattice of a metal or alloy. These interstitial sites are the empty spaces between the atoms of the host material. When hydrogen is absorbed by a metal, it can dissolve into these interstitial positions, forming a non-stoichiometric compound. The amount of hydrogen that can be absorbed depends on the metal or alloy and the environmental conditions such as temperature and hydrogen pressure.

The properties of the host material can be significantly altered by the presence of interstitial hydrogen. For instance, the mechanical properties might change, leading to phenomena like hydrogen embrittlement, where the material becomes brittle and prone to fracture. Electrical conductivity and magnetic properties can also be affected. The diffusion of hydrogen through these interstitial sites is a crucial aspect, influencing processes like hydrogen transport in fuel cells and hydrogen storage applications.

Research into interstitiaalihydriditbased materials is driven by their potential applications. These include hydrogen storage solutions for vehicles and stationary power, catalysis, and as components in advanced electronic devices. Understanding the interaction between hydrogen and the host lattice, including the thermodynamics and kinetics of hydrogen absorption and desorption, is key to designing materials with tailored properties for specific technological uses. The stability and reversibility of hydrogen absorption are critical factors for practical applications.
