Abstract:
Hydrogen storage alloys have attracted significant attention because of their high energy density and hydrogen storage ability under mild conditions. Some of these materials require hydrogen gas to be treated at high temperatures to store hydrogen. Ti2Ni is a promising hydrogen storage alloy owing to high hydrogen capacity and stability of its hydrides. This study demonstrates a hydrogen storage approach in Ti2Ni via hydrogen autotransfer. This reaction is an effective approach for C-N or C-C bond formation, utilizing unreactive alcohols dehydrogenation to form carbonyl compounds. The alloy exhibits catalytic activity in these reactions, and experimental studies, including X-ray diffraction and X-ray absorption spectroscopy, revealed the formation of Ti2Ni hydride using alcohols as hydrogen sources. This approach can be applied to common alcohols, such as ethanol and 2-phenethyl alcohol. A gaseous hydrogen detection experiment revealed that the amount of hydrogen released from Ti2Ni hydride reacted with alcohols was up to 0.68. This work represents the first report of the experimental verification of hydrogen being stored in a hydrogen storage alloy via a liquid-phase organic reaction. These findings offer an efficient approach for hydrogen storage using alcohols as hydrogen sources.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation reactions,...
Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
