“…The synthesis of zirconium nitride powders mainly includes direct nitridation of Zr metal with nitrogen 25,26 , high energy reactive ball milling (RBM) 27 , microwave plasma method 28 , benzene-thermal method 29 , aluminum reduction nitridation 30 , magnesium thermal reduction 31 , carbothermic reduction nitridation (CRN) 32 , and direct carbothermic nitridation (CN) of zirconia (ZrO 2 ) 33 and zircon 34 etc. CRN and CN processes are appropriate routes for various sizes and morphologies like particles 35–37 , fibers 38 , microspheres 21 , films 39 and bulk materials 20 , and have a great possibility of large-scale production of zirconium nitride and other transition metal nitrides.…”

Zirconium compounds has been widely attention over the last decades due to its excellent physical and chemical properties. Zirconium nitride nanopowders were synthesized via a simple direct carbothermic nitridation process of internal gel derived zirconia in the presence of nano-sized carbon black. The effects of reaction temperature, dwell time and molar ratio of carbon black to Zr (C/Zr) on the phase composition, grain size and crystal parameters of products were studied. Based upon the analysis of crystallite phase evolution and microstructure characterization, it was found that zirconium oxynitride is intermediate product and then O atoms in oxynitride were extracted by oxygen getter, carbon black. Anion sites were directly replaced by N atoms to form rock-salt type nitride in carbothermic nitridation process.

“…Optical characterization revealed a plasmonic resonance within the visible spectrum . ZrN nanoparticles have also been made by zirconium wire explosion in a nitrogen atmosphere, by pulsed wire discharge, and by microwave-mediated synthesis . None of these latter three processes succeeded in creating uniform small ZrN nanoparticles, and none of these particles were characterized optically. − …”

Plasmonic Core–Shell Zirconium Nitride–Silicon Oxynitride Nanoparticles

We discuss the synthesis and properties of plasmonic zirconium nitride nanocrystals produced using a nonthermal plasma reactor. The process enables the continuous conversion of chemical precursors into free-standing ∼10 nm diameter nanoparticles. Oxidation limits the resonant plasmon energy from ∼2.6 eV for ideal unoxidized particles to ∼2.1 eV for particles exposed to air at room temperature. A simple modification to the plasma process allows the inflight growth of a conformal silicon oxynitride shell onto the zirconium nitride core. The shell inhibits the oxidation of the core, resulting in particles with a plasmon energy of 2.35 eV. These particles show good plasmonic behavior even after annealing in air at 300 °C, largely improved when compared to unprotected particles that oxidize and lose plasmonic activity at the same temperature. This work represents a step toward the development of earth-abundant, thermally and chemically resistant nanoparticles that can offer an inexpensive alternative to gold and silver and extended applicability in harsh environments.

“…It is found that ZrN NPs have good crystallinity and a 0.26 nm lattice spacing, corresponding to the ZrN crystal plane (111) [30]. According to the SAED analysis of ZrN, these XRD peaks are attributed to (111), ( 200), (220), and (311), as shown in the inset of Figure 2f [31]. Figure 2g shows a TEM image of HfN, in which HfN NPs have a near-spherical morphology with few intergrowths and good dispersion.…”

Nanostructured transition metal nitrides (TMNs) have been considered as a promising substitute for precious metal catalysts toward ORR due to their multi-electron orbitals, metallic properties, and low cost. To design TMN catalysts with high catalytic activity toward ORR, the intrinsic features of the influencing factor on the catalytic activity toward ORR of nanostructured TMNs need to be investigated. In this paper, titanium nitride (TiN), zirconium nitride (ZrN), and hafnium nitride (HfN) nanoparticles (NPs) are highly efficient and synthesized in one step by the direct current arc plasma. TiN, ZrN, and HfN NPs with an oxidation layer are applied as the catalysts of hybrid sodium–air batteries (HSABs). The effect of the composition and structural attributes of TMNs on ORR catalysis is defined as follows: (i) composition effect. With the increase in the oxygen content, the catalytic ORR capability of TMNs decreases progressively due to the reduction in oxygen adsorption capacity; (ii) structure effect. The redistribution of the density of states (DOS) of ZrN indicates higher ORR activity than TiN and HfN. HSABs with ZrN exhibit an excellent cyclic stability up to 137 cycles (about 140 h), an outstanding rate performance, and a specific capacity of 2817 mAh·g−1 at 1.0 mA·cm−2.
