Single atomic cerium sites anchored on nitrogen-doped hollow carbon spheres for highly selective electroreduction of nitric oxide to ammonia

Atomically isolated and unsaturated Sb sites created on Sb2S3for highly selective NO electroreduction to NH3

“…32 In addition, upon feeding 15 NO gas, the resulting 1 H nuclear magnetic resonance (NMR, Fig. S8 †) spectra reveal the characteristic 15 NH 4 + doublets, whereas feeding Ar gas leads to the absence of 15 NH 4 + doublets. [51][52][53] Furthermore, the switching NO-Ar test (Fig.…”

“…[11][12][13][14] Nevertheless, the NORR effectiveness is greatly retarded by the sophisticated five-electron reaction process and severe competition from the hydrogen evolution reaction (HER), 1 and it is imperative to explore efficient NORR electrocatalysts capable of boosting the NO-to-NH 3 pathway with high selectivity. [15][16][17][18][19][20] Transition metal-based catalysts commonly exhibit high NORR activity owing to their partially occupied d-orbitals boosting NO adsorption. [21][22][23][24][25][26][27] Nevertheless, d-orbitals also favor the formation of metal-H bonds to trigger the competitive HER, giving rise to low NORR selectivity.…”

Bimetallic phosphoselenide nanosheets as bifunctional catalysts for 5-hydroxymethylfurfural oxidation and hydrogen evolution

“…[52][53][54][55] Compared with the FePSe 3 / NS (0.79 eV), after the Mn doping, the ΔG H* value of the Mn-FePSe 3 /NS becomes 0.33 eV (Fig. 6d), indicative of optimized HER kinetics, [56][57][58][59][60][61] which is responsible for the observed HER performance (Fig. 4).…”

Li–N2 Battery for Ammonia Synthesis and Computational Insight

“…Even with the high priority given to environmental issues, the HB process is still running and has long been considered for a century due to the irreplaceable role of ammonia . However, electrification of the chemical industry is the future trend of carbon emission reduction with the development of renewable energy. − …”
