Reduction of Alkenes: Asymmetric Catalytic Hydrogenation02:17

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

3.5K
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...

Catalysis

28.2K
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: Catalytic Hydrogenation

12.8K
Alkenes undergo reduction by the addition of molecular hydrogen to give alkanes. Because the process generally occurs in the presence of a transition-metal catalyst, the reaction is called 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...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Catalysis

Background:

  • Carbon dioxide reduction reaction (CO2RR) is crucial for sustainable chemical synthesis.
  • Developing selective catalysts for CO2RR to valuable products like ethanal remains a challenge.

Purpose of the Study:

  • To report a novel catalyst based on ferromagnetic hexagonal-close-packed (hcp) cobalt (Co) nanosheets (NSs) for selective CO2RR to ethanal (CH3CHO).

Main Methods:

  • Electrochemical reduction of CO2 using hcp Co NSs as catalysts.
  • Varying reduction potentials from -0.2 to -1.0 V (vs RHE) in 0.5 M KHCO3 solution.
  • Density functional theory (DFT) calculations to elucidate reaction mechanisms.

Main Results:

  • hcp Co NSs selectively produced ethanal as the major product across all tested potentials.
  • At -0.4 V, Faradaic efficiency (FE) for ethanal reached 60% with a current density of 5.1 mA cm-2 and mass activity of 3.4 A g-1.
  • Total FE for ethanal, ethanol, and methanol was 82%.

Conclusions:

  • The hcp Co catalyst demonstrates high selectivity for CO2RR to ethanal.
  • DFT calculations indicate intralayer electron transfer promotes [OC-CO]* coupling and suppresses complete hydrogenation, leading to selective CH3CHO formation.
