Published: Jan. 9, 2025

With the increasing demand for downstream ammonia products, research on fuel has received growing attention. Therefore, under "dual carbon" context, it is crucial to develop an energy-efficient and environmentally friendly method synthesis. Current indicates that electrocatalytic synthesis one of most promising methods. This study systematically summarizes three major factors influencing nitrogen reduction reaction (eNRR) catalysts synthesis: material optimization, structural design, engineering. In terms materials, precious-metal-based, non-precious-metal-based, metal-free eNRR are classified listed. By examination properties catalytic effects various metals non-metals in synthesis, materials with highest activity can be further identified. To enhance efficiency, strategies, such as vacancy creation, doping, interface engineering, facet changes size morphology active sites, have been summarized. integration reactions, including microscale activation, proton transfer, electron efficiency was discussed depth. Finally, urgent issues need addressed current were discussed, unique insights future development provided. review aims provide innovative ideas design improve rate selectivity catalysts.

Selective Nitrogen Reduction Reaction on Single-Atom Centers of Molybdenum-Based MXenes by Pulsing the Electrochemical Potential

Published: Jan. 1, 2025

Electrocatalytic reduction of dinitrogen is a promising route for sustainable production ammonia, although the selectivity challenge competing nitrogen (NRR) and hydrogen evolution reactions in aqueous electrolytes has not yet been solved. Single-atom catalysts (SACs) offer hope bridging this gap because they exhibit unique electronic structure reactivity catalytic transformations compared to conventional bulk materials. In addition, potential pulse experiments have shown that promote formation kinetically unfavorable products by efficiently modulating electrolyte at solid-liquid interface. So far, combination SACs NRR mutually exclusive, since are likely be degraded during anodic due metal dissolution. Using density functional theory calculations grand canonical framework, we demonstrate present communication molybdenum-based MXenes able overcome limitation: traditional SACs, form single-atom centers pulse, their SAC-like allows directed ammonia instead gaseous cathodic pulse. Our study paves way development high-performance materials with in-situ formed sites enable advances selective under applied bias.
