A doping element improving the properties of catalysis: in situ Raman spectroscopy insights into Mn-doped NiMn layered double hydroxide for the urea oxidation reaction

Xu Yang et al.

Summary: Elemental doping has been shown to enhance the performance of Ni-based hydroxides for the electrochemical urea oxidation reaction. This study investigates the mechanism behind the catalytic activity enhancement of bimetallic catalysts through Mn doping. The results reveal that Mn doping promotes the generation of high-valence (NiOOH)-O-III and increases the electrochemical reversibility of the Ni redox pair in NiMn layered double hydroxides (LDHs). Raman spectroscopy analysis provides direct evidence of the structural changes induced by Mn doping, including elongation of the Ni-O bond in NiOOH and increased phase structure disorder.

Porous palladium phosphide nanotubes for formic acid electrooxidation

Tian-Jiao Wang et al.

Summary: Developing an efficient catalyst for formic acid electrocatalytic oxidation reaction (FAEOR) is crucial for accelerating the commercial application of direct formic acid fuel cells (DFAFC). In this study, palladium phosphide (PdxPy) porous nanotubes (PNTs) with different phosphide content were successfully prepared through a self-template reduction method and phosphating treatment. The Pd3P PNTs with optimized phosphide content exhibited outstanding electroactivity and stability for FAEOR, mainly due to the strong electronic effect between Pd and P, which promoted the direct pathway of FAEOR and inhibited the occurrence of formic acid decomposition reaction. With its facile synthesis, excellent electroactivity, high stability, and unique selectivity, Pd3P PNTs have the potential to be an efficient anode electrocatalyst for DFAFC.

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.
