Jul 16, 2021 · Electrochemical N 2 reduction reaction (NRR) produces ammonia cleanly and sustainably via the net reaction of N 2 + (6H + + e −) → 2NH 3 at ambient conditions.

Mar 9, 2018 · We achieve both excellent NRR selectivity (~90%) and a significant boost to Faradic efficiency by 10 percentage points even at ambient operations by coating a superhydrophobic metal-organic framework (MOF) layer over the NRR electrocatalyst.

Herein, two-dimensional (2D) bimetal–MOFs (Co x Fe–MOF) nanosheets with a thickness of ∼10 nm are synthesized and employed for OER and NRR in alkaline medium.

Jan 10, 2018 · Detailed information on the CV and FTIR spectra of Au film in an Ar-saturated KOH electrolyte, infrared spectroscopy of ammonia–water, the CV of Pt film in a N 2-saturated KOH electrolyte, the calibration curve of the ammonia meter, the current–time plot of the Au foil, and the repeated FTIR experiment on NRR

Here, we report a high-performance Ru@Ti 3 C 2 MXene catalyst for an ambient electrocatalytic NRR. In a 0.1 M KOH electrolyte, the NH 3 yield of the Ru@MXene catalyst reached 2.3 μmol h −1 cm −2, furthermore, at −0.4 V (vs. RHE) the Faraday efficiency was 13.13%.

Aug 12, 2021 · queous sodium or potassium hydroxide (NaOH/ KOH) solutions are the standard basic/alkaline electrolytes for many of the most important energy storage processes, such as alkaline batteries, supercapacitors, overall water splitting (OWS), the nitrogen reduction reaction (NRR), the oxygen evolution reaction (OER), the hydrogen evolution reaction (H...

Sep 15, 2024 · Electrochemical nitrogen reduction reaction (NRR) is a promising alternative to Haber–Bosch process as it can produce ammonia under ambient conditions. However, the competitive hydrogen evolution reaction (HER) and poor nitrogen solubility cause low yields and Faradaic efficiencies for NRR.

Aug 29, 2019 · For electrochemical NRR, potentiostatic tests were conducted in N 2-saturated 0.1 M KOH, which was purged with purified N 2 for 30 min before the measurement.

Sep 26, 2019 · Here, we report an effective strategy to boost the NRR activity of less active copper nanocatalysts via modulating the electron density of Cu nanoparticles over a significant potential scale to...

Nov 16, 2021 · Electrochemical nitrogen reduction reaction (NRR) is intensively investigated by researchers for its potential to be the next-generation technology to produce ammonia. Many attempts have been made to explore the possibility of electrochemical ammonia production catalyzed by noble metals.
