Abstract:

The fabrication of highly efficient and stable non-noble metal hydrogen evolution reaction (HER) electrocatalysts is of paramount significance for alleviating the energy and environmental crises. Herein, nickel (Ni) nanoparticles anchored on a carbon layer dispersed on carbon materials (Ni/C) are synthesized via a facile one-step thermal treatment. The nanostructure can facilitate mass transfer, expose more active sites and promote hydrogen (H₂) gas release. Benefiting from these advantages, Ni/C-0.8 exhibits excellent electrocatalytic HER performance. The overpotential of Ni/C-0.8 is -132 mV at -10 mA cm^-2, and its Tafel slope is 117 mV dec^-1 in an alkaline solution. Additionally, Ni/C-0.8 exhibits remarkable stability during long-term testing. This work offers a new avenue for designing and fabricating non-noble metal electrocatalysts for the electrocatalytic HER.

Catalysis

Catalysis

The presence of a catalyst affects the rate of a chemical reaction. A catalyst is a substance that can increase the reaction rate without being consumed during the process. A basic comprehension of a catalysts’ role during chemical reactions can be understood from the concept of reaction mechanisms and energy diagrams.

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...
