New efficient intermetallide catalysts for hydrogen storage in reversible processes of aromatics hydrogenation and naphthene dehydrogenation were studied. These catalysts provide an enhanced activity in the dehydrogenation of saturated organic molecules, with no side reactions like cracking, hydrogenolysis, ring opening, or coke formation occurring on these catalysts. The use of intermetallides provides some hydrogen storage capacity in the low-temperature region, while their catalytic activity in the dehydrogenation affords the hydrogen supply in the high-temperature range.
Graphical abstractUp to 7.25 wt.% H2 can be stored in the system based on terphenyl with 1%Pt/Mg2Ni as a catalyst for the reversible hydrogenation and dehydrogenation processes.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Pt/LaNi5 or Pt/Mg2Ni are used as catalysts for H2 storage in reversible hydrogenation–dehydrogenation of aromatic. ► The H2 storage capacity reaches 7.25 wt.%, terphenyl is most suitable for the hydrogen storage.
