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:

The Haber-Bosch process for ammonia production is energy-intensive.
Electrolytic nitrate reduction to ammonia (NO₃^-RR) presents a sustainable alternative.
Developing efficient electrocatalysts is crucial for NO₃^-RR.

Purpose of the Study:

To develop a laser-assisted strategy for enhancing electrocatalyst performance.
To investigate the role of valence engineering in Mo-doped Cu₂O for NO₃^-RR.
To achieve high ammonia yield and Faraday efficiency via NO₃^-RR.

Main Methods:

Synthesized Mo-doped Cu₂O (Mo-Cu₂O/CF) via hydrothermal doping.
Applied laser treatment to modulate molybdenum valence states (Mo⁶⁺ to Mo⁴⁺).
Evaluated the catalyst's performance in NO₃^-RR at a concentration of 0.1 M.

Main Results:

The laser-treated catalyst (LG-Mo-Cu₂O/CF) demonstrated Mo⁴⁺ species promoting H₂O dissociation.
Achieved an NH₃ yield of 10.9 mg h^-1 cm^-2 at -0.5 V vs. RHE.
Obtained a high Faraday efficiency of 94.3% and a nitrate-to-ammonia conversion rate of 93.2%.

Conclusions:

Laser-enabled valence engineering is effective for enhancing NO₃^-RR electrocatalysts.
The low-valent Mo species facilitate the hydrogenation steps in NO₃^-RR.
The developed catalyst offers a promising low-energy pathway for sustainable ammonia production.
