Reduction of Alkenes: Asymmetric Catalytic Hydrogenation02:17

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

4.0K
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...

Catalysis02:50

Catalysis

32.1K
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.

Heterogeneous Catalysis01:22

Heterogeneous Catalysis

80
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...

Batteries and Fuel Cells

31.9K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide02:44

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

13.4K
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.

Electrolysis03:00

Electrolysis

31.5K
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...

Area of Science:

  • Electrochemistry
  • Catalysis
  • Green Chemistry

Background:

  • The electrochemical synthesis of hydrogen peroxide (H2O2) via the two-electron water oxidation reaction (2e-WOR) and oxygen reduction reaction (2e-ORR) offers a sustainable pathway.
  • A key challenge is identifying compatible catalysts for both reactions under identical conditions.

Purpose of the Study:

  • To develop and demonstrate a paired electrochemical cell for H2O2 production using efficient and compatible catalysts.
  • To establish a new benchmark for homogeneous dual-electrode H2O2 electrosynthesis.

Main Methods:

  • Utilized Cu(tmpa) as a catalyst for the 2e-ORR and Sn-TMPyP for the 2e-WOR.
  • Assembled a paired electrochemical cell for H2O2 production.
  • Employed a carbonate buffer electrolyte to enhance Sn-TMPyP catalytic performance.

Main Results:

  • The paired cell achieved a total overpotential of 570 mV.
  • Cathodic Faradaic efficiency for H2O2 production ranged from 15% to 19% (1.6 µmol h⁻¹ cm⁻²).
  • Anodic Faradaic efficiency stabilized between 40% and 50% (3.5 µmol h⁻¹ cm⁻²).

Conclusions:

  • Cu(tmpa) and Sn-TMPyP are effective and compatible catalysts for paired H2O2 electrosynthesis.
  • Sn-TMPyP exhibits high activity for 2e-WOR, particularly in a carbonate buffer.
  • This work sets a new benchmark for homogeneous dual-electrode H2O2 production.
