Abstract:
The sluggish charge transfer and poor intrinsic activity are the obstacles that limit the development for electrocatalysts on hydrogen evolution. A novel core-shell heterostructure composed of Cu3P nanowires with supported CoO nanosheets was synthesized. Owing to numerous active sites and synergistic effect, the as-prepared Cu3P@CoO was highly efficient for hydrogen evolution and outperformed the single component. The theoretical calculations demonstrate that Cu3P@CoO had a zero bandgap for the incorporation of metallic Cu3P, which can greatly accelerate the charge transfer. Besides, the adsorption free energy of intermediates on Cu3P@CoO can also be optimized, leading to a small energy barrier in the reaction pathway, and thereby an increased intrinsic activity. This work highlights the significance of exploiting the synergistic effect of the heterostructure on the charge transfer and intrinsic activity when designing highly efficient electrocatalysts for hydrogen evolution.

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.

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 Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
