Unveiling the Electrooxidation of Urea: Intramolecular Coupling of the N-N Bond

Wei Chen et al.

Summary: This study delves into the crucial role of nitrogenous nucleophile electrooxidation reaction (NOR) in the degradation and transformation of available nitrogen, particularly focusing on the transformation mechanism mediated by the beta-Ni(OH)(2) electrode. The study proposes the role of proton-coupled electron transfer (PCET) in bridging the electrocatalytic dehydrogenation and spontaneous nucleophile dehydrogenative oxidation reaction, with a specific focus on the urea oxidation reaction (UOR). Through both operando tracing and theoretical calculations, a mechanism for UOR involving intramolecular coupling of the N-N bond, accompanied by PCET, hydration, and rearrangement processes, is proposed to achieve high performance and approximately 100% N-2 selectivity. These findings shed light on the evolution of nitrogenous molecules during NOR, as well as fundamental aspects of electrocatalysis involving nitrogen-containing species.

Electrosynthesis of Nitrate via the Oxidation of Nitrogen on Tensile-Strained Palladium Porous Nanosheets

Shuhe Han et al.

Summary: Nitrate is an essential raw material in agriculture and industry, but the electrochemical nitrogen oxidation reaction (NOR) shows potential to replace traditional nitrate synthesis with high energy consumption and greenhouse gas emissions. Tensile-strained palladium porous nanosheets (Pd-s PNSs) were found to have enhanced activity for electrochemical NOR, outperforming Pd nanosheets. Experiments with N-15 isotope labeling confirmed that nitrate originates from nitrogen oxidation.

Tungsten Blue Oxide as a Reusable Electrocatalyst for Acidic Water Oxidation by Plasma-Induced Vacancy Engineering

Hanfeng Liang et al.

Summary: This research demonstrates that materials with intrinsically poor electrocatalytic activity can be transformed into active electrocatalysts for driving the acidic oxygen evolution reaction through ultrafast plasma sputtering. By introducing abundant oxygen vacancies, the surface electronic structures are reconstructed, leading to improved OER performance. This approach of defect chemistry provides a new direction for the discovery of acid-stable OER catalysts.

Electrochemical oxidation of molecular nitrogen to nitric acid - towards a molecular level understanding of the challenges

Megha Anand et al.

Summary: This work discusses the possible reaction mechanisms of electrochemical N-2 oxidation (N2OR) and its competition with the parasitic oxygen evolution reaction (OER) at the molecular level. The author suggests design strategies for N-2 oxidation electro-catalysts by comparing the performance of two catalysts and establishes trends/scaling relations to correlate OER and N2OR activities. The challenges associated with electrochemical N2OR are highlighted.
