Introduction to Mechanisms of Enzyme Catalysis

Introduction to Mechanisms of Enzyme Catalysis

For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes...

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.

Enzymes

Enzymes

Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

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...

Background:

Copper (Cu) clusters are effective catalysts for the electrocatalytic carbon dioxide reduction reaction (CO2RR).
The hydrogen evolution reaction (HER) often competes with CO2RR, reducing efficiency.
Tungsten ditelluride (WTe2) substrates can influence catalytic activity.

Purpose of the Study:

To investigate the CO2RR performance of small Cu clusters (Cu3, Cu8, Cu13) supported on a T"-WTe2 substrate.
To analyze the competition between CO2RR and HER on these supported clusters.
To understand the role of substrate-cluster interactions in catalytic efficiency.

Main Methods:

First-principles calculations were employed to systematically study the catalytic systems.
The CO2RR and HER pathways were investigated on Cu clusters anchored on T"-WTe2.
The effect of cluster size and substrate morphology on catalytic activity was analyzed.

Main Results:

Cu clusters supported on T"-WTe2 (Cu_n@T -WTe2) exhibit enhanced CO2RR activity compared to unsupported Cu clusters.
Catalytic performance improves with increasing Cu cluster size.
Cu13@T -WTe2 demonstrates superior CO2RR activity over HER, surpassing the performance of smaller clusters.
The buckled surface of T -WTe2 deforms the Cu13 cluster, optimizing CO2RR.

Conclusions:

T -WTe2 supported Cu clusters are promising catalysts for boosting CO2RR.
Optimizing Cu cluster size and substrate interaction is key to enhancing CO2RR selectivity.
This approach offers a strategy to suppress HER and promote CO2RR using WTe2-supported Cu clusters.
