Reduction of Alkenes: Catalytic Hydrogenation

Reduction of Alkenes: Catalytic Hydrogenation

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...

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation

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...

Chemiosmosis

Chemiosmosis

Oxidative phosphorylation is a highly efficient process that generates large amounts of adenosine triphosphate (ATP), the basic unit of energy that drives many cellular processes. Oxidative phosphorylation involves two processes— the electron transport chain and chemiosmosis.
Electron Transport Chain
The electron transport chain involves a series of protein complexes on the inner mitochondrial membrane that undergo a series of redox reactions. At the end of this chain, the electrons...

Nuclear Fusion

Nuclear Fusion

The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Potentiometry: Membrane Electrodes

Potentiometry: Membrane Electrodes

Membrane electrodes, also known as p-ion electrodes, use membranes that selectively interact with free analyte ions, generating a potential difference across the membrane. The resulting membrane potential, known as the asymmetry potential, is not zero even when analyte concentrations on both sides of the membrane are equal. The membrane's response is typically not selective to a single analyte but proportional to the concentration of all ions in the sample solution capable of interacting at...

Background:

Industrial hydrogenation relies heavily on fossil-derived hydrogen gas, contributing to significant carbon emissions.
Current electrochemical hydrogenation methods are often limited by low reactant concentrations and specific solvent requirements.

Purpose of the Study:

To develop and demonstrate a novel membrane reactor for hydrogenation that utilizes in-situ generated hydrogen from water via renewable electricity.
To overcome the limitations of conventional electrochemical hydrogenation, enabling reactions in diverse solvents and at high concentrations for improved scalability.

Main Methods:

Fabrication of a membrane reactor featuring a palladium (Pd) membrane separating electrochemical hydrogen production and chemical hydrogenation compartments.
Application of an electrochemical bias across the Pd membrane to drive hydrogen permeation and subsequent hydrogenation.
Utilized atmospheric mass spectrometry (atm-MS) to quantify hydrogen permeation and gas chromatography mass spectrometry (GC-MS) to assess reaction selectivity and yield.

Main Results:

Demonstrated efficient hydrogenation without direct H2 input, with a measured hydrogen permeation of 73% via atm-MS.
Achieved 100% selectivity in the hydrogenation of propiophenone to propylbenzene, as confirmed by GC-MS.
The membrane reactor design allows for hydrogenation in various solvents and at high concentrations, unlike traditional methods.

Conclusions:

The developed membrane reactor offers a sustainable and efficient alternative for industrial hydrogenation by sourcing hydrogen from water using renewable electricity.
The physical separation of hydrogen production and utilization in the reactor design significantly enhances its versatility, scalability, and commercial viability for greener chemical synthesis.
