Abstract:

A Ni(II)-based 3D metal-organic framework (MOF), Ni-MOF, and its bimetallic derivative, NiCo-MOF, synthesized hydrothermally, showed superior hydrogen evolution reaction (HER) electrocatalysis. NiCo-MOF demonstrates a 120 mV overpotential, 39 mV dec^-1 Tafel slope, and stable structure after 20 h at -0.12 V vs. RHE, while Ni-MOF shows a 150 mV overpotential, 52 mV dec^-1 Tafel slope, and degradation, highlighting the synergistic benefits of bimetallic systems in electrocatalysis.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
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...
