Thermal and Photochemical Electrocyclic Reactions: Overview

Thermal and Photochemical Electrocyclic Reactions: Overview

Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.

Background:

Electrocatalytic oxidation of ethylene glycol (EG) is vital for energy conversion and chemical synthesis.
Comprehensive theoretical studies on EG oxidation reaction landscapes are limited.

Purpose of the Study:

Investigate Pd-Cu core-shell nanoclusters for EG electrocatalytic oxidation.
Understand the influence of cluster size, atomic arrangement, and electronic properties on reaction pathways and stability.

Main Methods:

First-principles calculations were used to study 13- and 55-atom Pd-Cu nanocluster models.
Analyzed cluster stability, reaction pathways, and electronic properties, including d-band center and CO adsorption.

Main Results:

Cu-core/Pd-shell configuration enhances cluster stability.
Cu-rich surfaces preserve C-C bonds; Pd-rich surfaces promote C-C cleavage.
Cu doping optimizes CO adsorption, improving antipoisoning capability and reducing the Gibbs free energy for formic acid production.

Conclusions:

Pd-Cu nanoclusters offer a tunable strategy for designing poisoning-resistant electrocatalysts.
Atomic-level catalyst engineering provides a generalizable paradigm for fuel cells and electrosynthesis.
