氮化钛(TiN)材料因其独特的热稳定性、极高的硬度、低的生产成本和与金类似的光学性能，在过去的几年里引起了人们的兴趣。在本研究中，通过热苯法合成了纳米TiN，得到了黑色纳米粒子。用扫描电子显微镜(SEM)观察了样品的形貌。进一步的微观表征是将最终产物滴铸到双面导电碳带上，并溅射4 nm厚的金/钯，用场发射扫描电子显微镜(FE-SEM)和能量色散X射线能谱(EDS)进行表征，结果表明它们是球形的。用ImageJ软件测量颗粒的平均尺寸为79 nm。EDS被用来确定样品中存在的元素，并得出结论，不存在杂质。利用傅里叶变换红外光谱(FTIR)对TiN的特征峰进行了表征。X-射线衍射仪(X射线衍射仪)显示出立方相氮化钛的典型衍射峰，德拜-谢勒法测得其微晶尺寸为14 nm。动态光散射(DLS)分析揭示了TiN纳米粒子的尺寸分布，其平均直径为154 nm。Zeta电位推断，纳米锡颗粒表面带负电荷。
Titanium nitride (TiN) materials have gained an interest over the past years due to their unique characteristics, such as thermal stability, extreme hardness, low production cost, and comparable optical properties to gold. In the present study, TiN nanoparticles were synthesized via a thermal benzene route to obtain black nanoparticles. Scanning electron microscopy (SEM) was carried out to examine the morphology. Further microscopic characterization was done where the final product was drop cast onto double-sided conductive carbon tape and sputter-coated with gold/palladium at a thickness of 4 nm for characterization by field emission scanning electron microscopy (FE-SEM) with energy dispersive X-Ray spectroscopy (EDS) that revealed they are spherical. ImageJ software was used to measure the average size of the particles to be 79 nm in diameter. EDS was used to determine the elements present in the sample and concluded that there were no impurities. Further characterization by Fourier Transform infrared (FTIR) spectroscopy was carried out to identify the characteristic peaks of TiN. X-ray diffraction (XRD) revealed typical peaks of cubic phase titanium nitride, and crystallite size was determined to be 14 nm using the Debye-Scherrer method. Dynamic light scattering (DLS) analysis revealed the size distribution of the TiN nanoparticles, with nanoparticles averaging at 154 nm in diameter. Zeta potential concluded the surface of the TiN nanoparticles is negatively charged.
