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...

Catalysis

Catalysis

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.

Electrophilic Aromatic Substitution: Nitration of Benzene

Electrophilic Aromatic Substitution: Nitration of Benzene

The nitration of benzene is an example of an electrophilic aromatic substitution reaction. It involves the formation of a very powerful electrophile, the nitronium ion, which is linear in shape. The reaction occurs through the interaction of two strong acids, sulfuric and nitric acid.

Preparation of Amines: Reduction of Oximes and Nitro Compounds

Preparation of Amines: Reduction of Oximes and Nitro Compounds

Oximes can be reduced to primary amines using catalytic hydrogenation, hydride reduction, or sodium metal reduction. The reduction of aliphatic and aromatic nitro compounds to primary amines takes place by either catalytic hydrogenation or by using active metals like Fe, Zn, and Sn in the presence of an acid.
Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...

Background:

The Haber-Bosch process, while crucial for ammonia production, is energy-intensive and relies on fossil fuels.
Electrochemical ammonia synthesis offers a sustainable alternative but faces challenges with high overpotential and low selectivity in the nitrogen reduction reaction (NRR).

Purpose of the Study:

To address the limitations of current electrochemical ammonia synthesis methods.

Main Methods:

Synthesis of a Ru@Ti3C2 MXene catalyst.
Electrochemical testing of the catalyst in a 0.1 M KOH electrolyte for NRR.
Measurement of ammonia yield and Faraday efficiency.

Main Results:

The Ru@MXene catalyst achieved an NH3 yield of 2.3 μmol h-1 cm-2.
A Faraday efficiency of 13.13% was recorded at -0.4 V (vs. RHE).

Conclusions:

The developed Ru@MXene catalyst demonstrates high performance for ambient electrocatalytic NRR.
This catalyst presents a viable and sustainable alternative for ammonia synthesis, overcoming previous limitations.
