Abstract:
Herein, we report a scalable strategy to fabricate nitrogen-doped carbon containing nonmetal selenium (Se) single atoms (SAs), termed Se SA/NC, by hydrogen bonding and subsequent calcination. The Se SA/NC loading 3.2 wt % Se SAs displays the best electrocatalytic activity, as well as excellent stability for alkaline hydrogen evolution reaction (HER), which is superior or at least comparable to the reported noble metal-based electrocatalysts. The experimental and theoretical studies reveal that the Se SAs at a lower loading can largely lower the reaction barrier for remarkably enhanced alkaline HER. This research provides a feasible strategy for designing high-performance nonmetal SAs for HER.

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.
The hydrogenation process takes place on the...
