Electrocatalytic reduction of NO to NH3 (NORR) emerges as a promising route for achieving harmful treatment and sustainable generation. In this work, we first report that Mo2C is an active selective NORR catalyst. The developed nanosheets deliver high yield rate 122.7 μmol h-1 cm-2 with Faradaic efficiency 86.3% at -0.4 V. Theoretical computations unveil the surface-terminated Mo atoms on can effectively activate NO, promote protonation energetics, suppress proton adsorption, resulting in activity selectivity Mo2C.

Electrochemical nitrite (NO2-) reduction is a potential and sustainable route to produce high-value ammonia (NH3), but it requires highly active electrocatalysts. Herein, Cu nanoparticles anchored on TiO2 nanobelt array titanium plate (Cu@TiO2/TP) are reported as high-efficiency electrocatalyst for NO2--to-NH3 conversion. The designed Cu@TiO2/TP catalyst exhibits outstanding catalytic performance toward the NO2-RR, with high NH3 yield of 760.5 μmol h-1 cm-2 (237.7 mgcat.-1) an excellent faradaic efficiency 95.3% in neutral solution. Meanwhile, also presents strong electrochemical stability during cyclic tests long-term electrolysis.

Abstract Electrochemical ammonia synthesis (EAS) presents an attractive alternative to the Haber–Bosch process due benefits of energy saving, low carbon emission, environmental friendliness, and so on. However, competing hydrogen evolution reaction (HER) severely limits yield, selectivity, current efficiency NH 3 . Although accumulation self‐aggregation active (H*) are primary causes HER, it also serves as critical species intermediate for multistep hydrogenation deoxygenation processes. Therefore, sensible regulation H* generation consumption essential enhancing EAS performance. And is significant thoroughly review strategies control. Herein, a comprehensive introduction provide fundamental understanding its role in electrochemical reactions, including generation, conversion, identification, quantification protocols first proposed. In addition, control carefully summarized with particular focus on regulating enhance activity, Faradaic efficiency. Finally, remaining challenges perspectives discussed.

Electrocatalytic overall water splitting (OWS), powered by a renewable energy source, is promising strategy for hydrogen production. However, the OWS system usually requires large consumption due to sluggish kinetics of anodic oxygen evolution reaction. Herein, we fabricated PtCu nanoalloy (PtCu-NA) through template-assisted method and evaluated its bifunctional activities both reaction (HER) in 1 M KOH hydrazine oxidation (HzOR) + hydrazine. Remarkably, interplanar crystal spacing PtCu-NA was larger than that standard closer Pt, which can be attributed synthesis method. Thus, as-prepared needs low overpotentials 224 668 mV drive HER HzOR at 100 200 mA cm–2, respectively, are much better those commercial Pt/C (453 1081 mV). After coupling together, (OHzS) cell small voltage 0.666 V deliver cm–2 hydrazine, outperforming (0.792 V). Impressively, assembly OHzS could run stably more 110 h. These performances regulation structure alloy synergistic effect between Pt Cu.
