Special Issue Information

Dear Colleagues,

The efficient electrochemical conversion of renewable energy sources represents a central challenge in sustainable energy science. Electrocatalysts, serving as the critical interface for key reactions, such as hydrogen and oxygen evolution and CO2, nitrogen, and nitrate reduction, govern the kinetic and thermodynamic limits of these processes. Advancing the field requires a fundamental understanding of structure–activity–stability relationships at the atomic scale, alongside the rational design of materials that surpass the limitations of conventional catalysts. This Special Issue will highlight cutting-edge research on electrocatalytic materials and mechanisms, spanning interfacial engineering, operando characterization, computational modelling, and device integration. We aim to foster interdisciplinary advances toward developing efficient, durable, and cost-effective electrocatalytic systems for a carbon-neutral energy future.

If you would like to submit papers for publication in this Special Issue or have any questions, please contact the in-house Editor, Ms. Georgie Guan (georgie.guan@mdpi.com).

Electrocarboxylation of aromatic halides with carbon dioxide (CO2) to high-value aromatic carboxylic acids under mild conditions offers a promising approach for CO2 resource utilization and the preparation of valuable aromatic carboxylic acids. However, studies on the electrocarboxylation of heterocyclic halides with CO2 remain relatively limited, and, in particular, the electrocarboxylation of thiazole halides with CO2 has not yet been reported in the literature. Herein, the electrocarboxylation of bromothiazoles (BTs) with CO2 was successfully achieved on a silver (Ag) cathode and a Magnesium (Mg) anode under mild conditions, yielding the corresponding thiazole carboxylic acids (TCAs). Using 4-bromothiazole (4-BT) as a model substrate, the effects of solvent, supporting electrolyte, electrode material, current density, charge passed (Q), and temperature on the yield of the target product 4-thiazolecarboxylic acid (4-TCA) were systematically investigated. Under optimized reaction conditions, this electrocarboxylation strategy proceeded smoothly to other BTs, providing synthetically useful TCAs with moderate to good yields and FEs. Additionally, the electrochemical behavior of bromothiazole on the Ag electrode was investigated using cyclic voltammetry, and a possible reaction mechanism for the formation of the carboxylated product was proposed based on the results.
