Nitrogen fixation using plasma electrolysis is an alternative in the production of liquid nitrate fertilizer which safe for environment because it does not produce emissions that pollute environment. The effectiveness shown from position formation at cathodic and anodic levels. This study aims to analyze comparison levels producing nitrate. Current-voltage characterization carried out determine formation. glow discharge achieved after critical voltage (280 V) lower than (650 V). Measurement emission intensity electron spin resonance reactive species play a role plasma. Nitrate influenced by form N, N2*, N2+, •OH, •H •O, especially nitrogen •OH are needed both NO pathway (anodic plasma) ammonia (cathodic plasma). results this showed was more effective synthesis. produced 1889 mg L-1, greater as much 213 L-1.

Interstitial Boron-Modulated Porous Pd Nanotubes for Ammonia Electrosynthesis

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(6), P. 3099 - 3106

Published: Feb. 1, 2024

Electrochemical conversion of nitrogen into ammonia at ambient conditions as a sustainable approach has gained significant attention, but it is still extremely challenging to simultaneously obtain high faradaic efficiency (FE) and NH3 yield. In this work, the interstitial boron-doped porous Pd nanotubes (B–Pd PNTs) are constructed by combining self-template reduction method with boron doping. Benefiting from distinctive one-dimensional nanotube architectonics incorporation B atoms, resulting B–Pd PNTs exhibit yield (18.36 μg h–1 mgcat.–1) FE (21.95%) in neutral conditions, outperforming Pd/PdO (10.4 mgcat.–1 8.47%). The present study provides an attractive enhance electroreduction incorporating Pd-based catalysts.

Two‐dimensional Boridene Nanosheets for Efficient Electrochemical Nitrogen Fixation under Ambient Conditions

ChemSusChem, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 9, 2024

Abstract The carbon‐free electrocatalytic nitrogen reduction reaction (NRR) is an alternative technology to the current Haber‐Bosch method, that can be conducted under ambient conditions, and directly converting water (N₂) into ammonia (NH₃). However, limited activity selectivity of NH₃ electrosynthesis hinder practical applications NRR. In this study, we present a novel type electrocatalyst called boridene nanosheets enriched with metal vacancies are specifically designed for efficient NRR conditions. Electrochemical testing in 0.1 M phosphate‐buffered saline (PBS) electrolyte demonstrates exhibits high Faradaic efficiency 66.7 % production at −0.2 V vs. RHE, maximum yield rate 23.6 μg h −1 mg cat −0.4 RHE. Durability tests show maintains significant stability throughout multiple cycles Mechanistic insights obtained through situ Fourier transform infrared spectroscopy, revealing preference distal pathway during process These findings highlight potential as stable catalyst sustainable synthesis.
