Abstract Renewable energy driven N 2 electroreduction with air as nitrogen source holds great promise for realizing scalable green ammonia production. However, relevant out-lab research is still in its infancy. Herein, a novel Sn-based MXene/MAX hybrid abundant Sn vacancies, Sn@Ti CT X /Ti SnC–V, was synthesized by controlled etching SnC MAX phase and demonstrated an efficient electrocatalyst electrocatalytic reduction. Due to the synergistic effect of heterostructure, existence vacancies highly dispersed active sites, obtained SnC–V exhibits optimal NH 3 yield 28.4 µg h −1 mg cat excellent FE 15.57% at − 0.4 V versus reversible hydrogen electrode 0.1 M Na SO 4 , well ultra-long durability.

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.

The development of an efficient, selective, and durable catalysis system for the electrocatalytic N2 reduction reaction (ENRR) is a promising strategy sustainable production ammonia. high-performance ENRR limited by two major challenges: poor adsorption over catalyst surface abysmal solubility in aqueous electrolytes. Herein, with help our combined density functional theory (DFT) calculations experimental electrocatalysis study, we demonstrate that concurrently induced electron-deficient Lewis acid sites electrocatalyst electrolyte medium can significantly boost performance. DFT calculations, ex situ X-ray photoelectron FTIR spectroscopy, electrochemical measurements, N2-TPD (temperature-programmed desorption) boron-doped strontium titanate (BSTO) samples reveal acid-base interactions synergistically enhance activation N2. Besides, B-dopant induces defect (oxygen vacancies Ti3+) assist enhanced results suppressed hydrogen evolution due to B-induced H+ adsorption. insights from study evince B prefers Srtop position (on top Sr) where adsorbs end-on configuration, which favors associative alternating pathway suppresses competitive evolution. Thus, demonstrates insight toward enhancing performance along via engineered at electrode interfaces.
