Tungsten Nitride/Tungsten Oxide Nanosheets for Enhanced Oxynitride Intermediate Adsorption and Hydrogenation in Nitrate Electroreduction to Ammonia

Continuous regulation of Cu electronic states by rectifying Schottky contacts enhancing electrochemical nitrate reduction to ammonia

“…Moreover, the peak at 1091 cm −1 belonging to the –N–O– stretching vibration of hydroxylamine (NH 2 OH) was also observed for both samples. 42 Compared to Cu@C, Cu@N 1.0 C exhibits a comparatively positive potential for NH 2 OH formation and significantly stronger intensity, in accordance with the strong substrate adsorption and conversion efficiency of Cu@N 1.0 C. The appearance of distinct N–H stretching and bending vibration of NH 4 + at 3687 and 1400 cm −1 further proves the formation of NH 3 . 43,44…”

Symmetry-breaking structure electrocatalysts for nitrate reduction to ammonia

“…In recent years, research on developing heterogeneous interface catalysts for the reduction of nitrate to produce ammonia has been gradually gaining momentum. 71–73 The significant coupling effect of heterogeneous interfaces optimizes their surface electronic structure, leading to catalysts with enhanced catalytic performance. 74 Lv et al recently reported a catalyst composed of FeP 4 and Ni 2 P (Fig.…”

Schottky Junctions with Bi@Bi2MoO6 Core-Shell Photocatalysts toward High-Efficiency Solar N2-to-Ammonnia Conversion in Aqueous Phase

“…Ammonia (NH 3 ) is one of the most essential fundamental industrial chemicals owing to its roles in carbon-free energy storage and the production of fertilizer [1][2][3]. The Haber-Bosch process for industrial synthetic ammonia requires greatly harsh conditions operating at a very high temperature (≈700 K) and very high pressures (≈100 atm), which result in great energy consumption and environment-harmful gas emissions [4][5][6].…”
