Ce-doped MoS_2−xnanoflower arrays for electrocatalytic nitrate reduction to ammonia

Abstract

Electrocatalytic reduction of nitrate to ammonia (NO3RR) represents a highly appealing route for achieving both value-added NH3 synthesis and facile removal of waste nitrate. In this study, Ce-doped and S-vacancy-enriched...

p-Block Antimony Single-Atom Catalysts for Nitric Oxide Electroreduction to Ammonia

“…Such strong Sb 1 –O 5 electronic coupling enables Sb to be atomically dispersed and strongly immobilized on a-MoO 3 , leading to a high structural stability of Sb 1 /a-MoO 3 (Figure S8). Further PDOS analysis (Figure S9) demonstrates that Sb 1 incorporation is able to effectively tune the electronic structure of a-MoO 3 to endow Sb 1 /a-MoO 3 with a reduced band gap and enhanced occupied electron states crossing the Fermi level, thereby accelerating the electron transport and reaction kinetics in the electrocatalytic NORR process. − …”

Self-Tandem Electrocatalytic NO Reduction to NH3 on a W Single-Atom Catalyst

“…Such strong W 1 –O 5 electronic interactions allow W to be atomically dispersed and firmly stabilized in MoO 3– x , resulting in a high thermodynamic stability of W 1 /MoO 3– x (Figure S10). Furthermore, in comparison with the MoO 3 semiconductor, both MoO 3– x and W 1 /MoO 3– x exhibit the occupied electron states across the Fermi level (Figure S11) and reduced work function (Figure S12), thus rendering W 1 /MoO 3– x with enhanced conductivity to accelerate the electron transfer and catalytic kinetics. − …”

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

“…S19 †) This journal is © The Royal Society of Chemistry 2023 curves and integrated RDF curves (Fig. S20 †), verifying the priority of In 1 /a-MoO 3 for the absorption and coverage of NO over H. [63][64][65][66] Therefore, in addition to promoting the NO hydrogenation energetics, single-site In can facilitate HER suppression to enable the achievement of a high NORR selectivity.…”
