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.

Background:

Single-atom catalysis relies on metal-support interactions for stability and reactivity.
Two-dimensional materials like graphene are common supports, with single-atom alloys (SAAs) gaining attention.
Goldene, a 2D gold monolayer, was recently synthesized as a potential graphene analogue.

Purpose of the Study:

To explore single-atom catalysts (SACs) with transition metal (TM) atoms supported on goldene.
To investigate the stability and catalytic performance of these TM-goldene systems.
To compare their reactivity against TMs on bulk gold(111).

Main Methods:

Electronic structure calculations were employed.
Stability under reducing and oxidizing conditions was assessed.
Catalytic performance for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) was evaluated.

Main Results:

Several stable TM-goldene systems were identified under various conditions.
Certain TM-goldene systems demonstrated promising HER and OER activity.
Reactivity differed significantly compared to TMs on bulk Au(111).

Conclusions:

TM-goldene SACs offer potential for enhanced stability and catalytic reactivity.
This study provides theoretical evidence for goldene as a novel support material.
The findings suggest new avenues for designing advanced single-atom catalysts.
