Abstract:
A magnesiothermic reduction route has been presented to synthesize phase-pure germanides that are not readily available traditionally. The obtained ruthenium germanide (RuGe) serves as an efficient non-Pt electrocatalyst for hydrogen evolution, and its intrinsic activity is very close to that of Pt. Our combined theoretical and experimental study demonstrates that the remarkable performance is derived from the germanium-induced change in hydrogen site preference from hollow to efficient Ru top sites.

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...
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.

Regioselectivity of Electrophilic Additions to Alkenes: Markovnikov's Rule
The hydrohalogenation of an unsymmetrical alkene can yield two haloalkane products, depending on which vinylic carbon takes up the halogen. However, one product usually predominates, where hydrogen adds to the vinylic carbon bearing the...
