With global efforts to relieve the formidable impact of climate change, hydrogen is considered a viable replacement for fossil fuels without intermittency concerns other renewable sources. Hydrogen storage plays pivotal role in implementation economy, coupling production with fuel cell technologies. Storing form solid-state hydride materials has been studied as future technology enabling safe, energy-efficient, and high-energy-density system. However, hostile thermodynamic kinetic properties each material result insufficient performance practical applications, such sluggish absorption or desorption, high dehydrogenation temperatures, sometimes limited reversibility; thus, these characteristics need be thoroughly understood depending on material. Among various strategies, nanostructuring regarded general approach tackling limitations regarding materials. In particular, formation nanosized hydrides within nanostructured scaffold─also known nanoconfinement─is great potential advanced because it can additionally leverage host–guest interactions at nanointerfaces scaffolds. this context, active tuning brings about additional changes sorption reactions compared unmodified nanoconfined composites, holding promise tailored strategies metal hydride. Perspective, we summarize major barriers highlight recent progress overcoming limits, mainly focusing nanointerface engineering hydrides. Further, provide our insight current challenges understanding underlying mechanisms interaction nanointerface, whereby noticeable technological leaps emulated systems.
