Preparation of titanium nitride nanoparticles from a novel refluxing derived precursor

Abstract

Titanium nitride (TiN) nanoparticles were prepared from a novel refl uxing-derived precursor. The organic/inorganic hybrid precursor was prepared by a two-stage refl uxing method using hydrous TiO 2 as titania source and n-dodecane as carbon source. The precursor was heat-treated to 1 200 °C in fl owing ammonia (NH 3 ) to get TiN nanoparticles. The phase and chemical compositions were investigated by means of XRD, Raman spectroscopy and XPS. Samples microstructure was studied by means of SEM, TEM and SEAD. XRD pattern indicated that the product was face-centered cubic TiN with a lattice constant a = 4.236 Å and average crystallite sizes of 35.2 nm. Raman spectra indicated that long time refl uxing results in Alkane dehydrogenation and the formation of coke on TiO 2 nanoparticles. Oxygen presence in TiN lattice was confirmed by XPS investigation. The particle size that was showed by Electron microscopy photographs ranged from 20 to 60 nm.

Plasmonic Titanium Nitride Nano-enabled Membranes with High Structural Stability for Efficient Photothermal Desalination

“…Here, we first characterized the size, morphology, and size distribution of TiN NPs using TEM. The representative TEM micrograph of TiN NPs illustrated in Figure S4 reveals the cubic morphology of the TiN particles, reflecting the cubic nature of TiN . The TiN NP size distribution calculated from the TEM micrographs using ImageJ is presented in Figure a.…”

“…The representative TEM micrograph of TiN NPs illustrated in Figure S4 reveals the cubic morphology of the TiN particles, reflecting the cubic nature of TiN. 29 The TiN NP size distribution calculated from the TEM micrographs using ImageJ is presented in Figure 1a. It can be seen that the TiN NPs used for the photothermal membrane fabrication had a moderately broad size distribution in the range of 30−60 nm (an average particle size of 45.11 ± 3.4 nm).…”

Review on Stability, Thermophysical Properties, and Solar Harvesting Applications of Titanium Nitride-Based Nanofluids: Current Status and Outlook

“…Due to the requirement of high temperature or intricate procedures for certain methods mentioned above, there is also a strong possibility of the presence of highly carbonaceous or coke species after combustion. Liu et al 109 employed a twostage refluxing method utilizing hydrous TiO 2 and n-dodecane as source materials to produce highly efficient TiN NPs. The final product exhibited minimal agglomeration, which can be attributed to the extremely small size of the sample.…”
