Abstract:
Here, we report two-dimensional (2D) Ni-Co hydroxide monolayers (NiCo-HMs) as a highly active cocatalyst for enhancing the photocatalytic H2 evolution of 2D g-C3N4 nanosheets. The NiCo-HMs can expand the interface of electron migration, promote the separation of photogenerated carriers, provide synergistic Co-Ni active sites, and optimize atomic hydrogen adsorption to improve the kinetics of the catalytic reaction. The resulting 2D/2D NiCo-HMs/g-C3N4 heterojunction displays a high photocatalytic H2 evolution of 3.58 mmol g-1 h-1.

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...
