摘要
在本研究中,我们提出了一种利用快速、简便、环保的非热等离子体方法剥离氮化钛(TiN)粉末的新方法。这种方法使用电弧和氮气作为环境气体,在室温下产生电离粒子。这些电离粒子与钛镍陶瓷晶体相互作用,产生明显的结构膨胀。利用透射电子显微镜、X 射线衍射和拉曼光谱对剥离的 TiN 产品进行了全面表征。值得注意的是,TiN 的立方晶体结构得到了有效保留,而 (200) 晶面 d 间距从 2.08 Å 增加到 3.09 Å,同时晶体尺寸减小,拉曼振动模式也发生了变化。总之,这些发现为利用我们创新的非热等离子体方法成功剥离 TiN 结构提供了令人信服的证据,为先进材料的应用开辟了令人兴奋的可能性。
Exfoliation of titanium nitride using a non-thermal plasma process.
In this study, we present a novel approach for the exfoliation of titanium nitride (TiN) powders utilizing a rapid, facile, and environmentally friendly non-thermal plasma method. This method involves the use of an electric arc and nitrogen as the ambient gas at room temperature to generate ionized particles. These ionized species interact with the ceramic crystal of TiN, resulting in a pronounced structural expansion. The exfoliated TiN products were comprehensively characterized using transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. Remarkably, the cubic crystal structure of TiN was effectively retained, while the (200) crystal plane d-spacing increased from 2.08 to 3.09 Å, accompanied by a reduction in crystallite size and alterations in Raman vibrational modes. Collectively, these findings provide compelling evidence for the successful exfoliation of TiN structures using our innovative non-thermal plasma method, opening up exciting possibilities for advanced material applications.
