Theoretical Assessment of Dinitrogen Fixation on Carbon Atom [PDF]

Chemistry - an Asian Journal, 2021
Abstract Dinitrogen activation in non‐metallic systems has received considerable attention in recent years. Herein, we report the theoretical feasibility of N 2 fixation using aminocarbenes ( L ) or their anionic derivatives.

Spectroscopic Identification of the Dinitrogen Fixation and Activation by Metal Carbide Cluster Anions PtCn- (n = 4-6).

Inorganic Chemistry, 2022
Nitrogen fixation is confronted with great challenges in the field of chemistry. Herein, we report that single metal carbides PtCn- and PtCnN2- (n = 4-6) are indispensable intermediates in the process of nitrogen fixation by mass spectrometry coupled ...

An exfoliated iron phosphorus trisulfide nanosheet with rich sulfur vacancy for efficient dinitrogen fixation and Zn-N2 battery

, 2021
Two-dimensional (2D) transition metal compounds have been explored as promising catalysts in dinitrogen electroreduction (NRR) for ammonia synthesis, while the immense basal planes of the 2D materials are inert towards the electrocatalysis.

Fixation of Dinitrogen at an Asymmetric Binuclear Titanium Complex

Inorganic Chemistry, 2021
A new type of dititanium dinitrogen complex supported by a triphenolamine (TPA) ligand is reported. Analysis by single-crystal X-ray diffraction and Raman and NMR spectroscopy reveals different coordination geometries for the two titanium centers.

The evolution of dinitrogen fixation

Origins of Life, 1984
It is argued that nitrogenase originated monophyletically in obligate anaerobes similar to Clostridia. The enzyme system was later inherited, without much change, by photosynthetic bacteria, by prokaryotic plants (blue-greens) and by aerobic bacteria.

Dinitrogen fixation in the world's oceans

Biogeochemistry, 2002
The surface water of the marine environment has traditionally been viewed as a nitrogen (N) limited habitat, and this has guided the development of conceptual biogeochemical models focusing largely on the reservoir of nitrate as the critical source of N to sustain primary productivity.

Biological dinitrogen (N2) fixation: introduction and nonsymbiotic

, 2021
In this chapter you will be introduced to some of the fundamentals of the process of biological N2 fixation and the nature of the enzyme complex, nitrogenase, which mediates the conversion of N2 to NH3.

Dinitrogen fixation by a thermophilic methanogenic bacterium

Nature, 1984
Methanogenic bacteria are known to use NH+4 as a nitrogen source for growth. Previous work with an impure methanogenic culture suggested that a methanogen might fix atmospheric dinitrogen as a nitrogen source, but no further work on this phenomenon has been documented.
