Rare-earth La-doped VS_2−xfor electrochemical nitrate reduction to ammonia

Abstract

Electrochemical nitrate reduction to ammonia (NO3RR) represents a fascinating approach to realize both green NH3 generation and wastewater purification, but it is urgently required to explore efficient catalysts to promote...

Main-group indium single-atom catalysts for electrocatalytic NO reduction to NH3

“…2b), In 1 /a-MoO 3 shows a distinct peak located at 1.61 Å, which is ascribed to the In-O coordination bond. The absence of the In-In coordination bond (2.97 Å) indicates that In presents as an isolated atomic state, [49][50][51][52] consistent with the AC-HAADF-STEM observation (Fig. 1e).…”

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

“…S8†) spectra reveal the characteristic 15 NH 4 + doublets, whereas feeding Ar gas leads to the absence of 15 NH 4 + doublets. 51–53 Furthermore, the switching NO–Ar test (Fig. S9†) reveals significant NH 3 production in NO cycles, whereas NH 3 is nearly undetectable in Ar cycles.…”

Amorphous NiB2for electroreduction of NO to NH3

“…Since the HER is the major competing reaction for the NORR, [57][58][59][60][61] the HER activity of the NORR-favored Ni site is further examined to assess its NORR selectivity. As shown in Fig.…”
