New Findings on Hydrogen Described by Investigators at Kyoto University (Hydrogen storage in Pd nanocrystals covered with a metal-organic framework)

August 29, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Hydrogen. According to news reporting originating in Kyoto, Japan, by NewsRx journalists, research stated, "Hydrogen is an essential component in many industrial processes. As a result of the recent increase in the development of shale gas, steam reforming of shale gas has received considerable attention as a major source of H-2, and the more efficient use of hydrogen is strongly demanded."

The news reporters obtained a quote from the research from Kyoto University, "Palladium is well known as a hydrogen-storage metal and an effective catalyst for reactions related to hydrogen in a variety of industrial processes. Here, we present remarkably enhanced capacity and speed of hydrogen storage in Pd nanocrystals covered with the metal-organic framework (MOF) HKUST-1 (copper(II) 1,3,5-benzenetricarboxylate). The Pd nanocrystals covered with the MOF have twice the storage capacity of the bare Pd nanocrystals. The significantly enhanced hydrogen storage capacity was confirmed by hydrogen pressure-composition isotherms and solid-state deuterium nuclear magnetic resonance measurements."

According to the news reporters, the research concluded: "The speed of hydrogen absorption in the Pd nanocrystals is also enhanced by the MOF coating."
