Ti-doped iron phosphide nanoarrays grown on carbon cloth as a self-supported electrode for enhanced electrocatalytic nitrogen reduction

Abstract

Electrocatalytic nitrogen reduction reaction (eNRR) has been widely recognized as a promising technology for green ammonia synthesis. However, the inert N≡N bond, inferior catalytic activity and small electrochemical active area...

Photoelectrochemical-driven nitrogen reduction to ammonia by a Vo-SnO2/TiO2 composite electrode

“…In recent years, electrocatalytic nitrogen fixation 7–10 and photocatalytic nitrogen fixation 11–14 have developed rapidly. The technology of photoelectrochemical (PEC) catalytic nitrogen fixation, combining electrocatalysis and photocatalysis, is regarded as a significant development direction for NH 3 synthesis and is expected to replace the traditional Haber–Bosch process.…”

Construction of a BiVO4/VS-MoS2 S-scheme heterojunction for efficient photocatalytic nitrogen fixation

“…3,4 This traditional method requires high temperature and pressure (300-550 °C and 15-25 MPa), resulting in signicant investment costs and high energy consumption. 5,6 Therefore, the pursuit of synthetic processes under mild conditions has become a paramount objective. Photocatalytic N 2 xation, employing semiconductor photocatalysts that harness sunlight as the energy source while utilizing N 2 and H 2 O as reactants, stands out as a sustainable approach for NH 3 production.…”

Molybdenum-Modified Titanium Dioxide Nanotube Arrays as an Efficient Electrode for the Electroreduction of Nitrate to Ammonia

“…However, the N≡N bond energy is notably high at 941 kJ mol −1 , and N 2 only dissolves sparingly in water [ 13 ]. Consequently, the energy utilization of nitrogen reduction reactions in the aqueous environment is limited, with NH 3 production yields up to three orders of magnitude lower than those of the Haber–Bosch process [ 14 ]. Considering this, researchers have explored other nitrogen-containing compounds as NH 3 synthesis sources and identified NO 3 − as a promising candidate.…”
