TiN 是一种极其坚硬的陶瓷材料, 具有显著的热稳定性、化学稳定性和机械稳定性。Tin 具有独特的光学特性, 可用于可访问近红外光 14, 15 的等离子体应用。研究表明, TiN 可以产生电磁场增强, 类似于 Au 纳米结构 16.演示了用于tin 基板的17或银17 或银18、19、20的沉积.然而, 很少对 Au/TiN 复合材料进行应用研究。Shiao 等人最近证明了 Au Dnfs/tyn 复合材料在光电化学细胞21和化学降解 22中的潜在应用。
Au 可以通过使用 FAGRR23 在tin 基板上合成。Au Dnf 在 TiN 上的沉积条件对应用性能至关重要。本研究考察了 Au Dnf 在 tin 涂层硅基板上的生长情况。

growth of gold dendritic nanoforests on titanium nitride-coated silicon substrates

本研究采用大功率脉冲磁控溅射系统, 在硅 (Si) 晶片上涂覆扁平牢固的氮化钛 (TiN) 薄膜, 并采用含氟辅助电置换反应 (FAGR) 对金进行快速、简便的沉积。树状纳米森林 (Au Dnf) 在 TiN/Si 基板上。扫描电子显微镜 (SEM) 图像和 Tin/Dnfs/Tin/si 样品的能量色散 x 射线光谱模式验证了合成过程的准确控制。在本研究的反应条件下, Au Dnf 的厚度在反应15分钟内线性增加到5.10±0.20μm。因此, 所采用的合成方法是制备 au Dnfss/tinssi 复合材料的一种简便、快速的方法。

Growth of Gold Dendritic Nanoforests on Titanium Nitride-coated Silicon Substrates

本研究提出了在氮化钛硅基板上合成金树突状纳米森林的可行方法。金树状纳米森林的厚度在合成反应后15分钟内呈线性增加。

该协议是一种简单、快速、电解沉积的方法，用于在钛氮化涂层硅基板上制备金树突纳米森林。这种技术的主要优点是它的简单性和速度。金树突纳米森林可以诱导质膜热点，增强质质光催化反应。也可以使用这个程序来准备合金金属如银的树突纳米森林。通过视频演示，在实验中更容易强调基本细节。要开始该程序，请切割 10 两片两厘米的 n 型硅晶片。在丙酮、异丙醇和去电化水中按顺序对硅样品进行五分钟的声波化。在氮气流下干燥样品五分钟。然后，将清洁干燥的硅样品放入样品架中，然后将支架放入 HiPIMS 样品室。将直径四英寸的钛合金目标放在HiPIMS溅射阴极上，然后泵下HIPIMS室的8倍10到负6托。在硅样品上沉积50纳米的钛合金层。然后，沉积氮化钛，实现氮化钛总厚度约300纳米。当氮化钛沉积完成时，将一种摩尔氯酸的240微升、8毫升的6至1个缓冲氧化物蚀刻和15.76毫升的去离子水混合在聚四氟乙烯容器中。将一个基板浸入氯尿酸溶液中精确三分钟，然后用去维化水清洗。在氮气流下干燥样品，并在120摄氏度下孵育5分钟。对剩余的氮化钛涂层基材重复此工艺。样品制备完成后，用扫描电子显微镜和X射线衍射对样品进行表征。X射线光谱的能量分散证实，金结构已经生长在钛氮化涂层硅表面。沉积在硅晶片上的氮化钛薄膜光滑均匀。在将样品放入生长溶液的一分钟内，小金核出现在样品中，并出现了几个类似于海胆的较大核。单树状结构在生长三分钟后观察到，分支发生在生长五分钟后。10分钟后，树突纳米森林覆盖了整个亚硝酸钛表面。15分钟后，树突纳米森林密密麻麻，厚约5微米。发现金的树突纳米森林厚度随着合成时间而呈线性增加。X射线衍射中的金峰也随着时间的推移而增加，而钛亚硝酸盐信号随着合成的进展而消失。尝试此程序时要记住的最重要的事情是组成率和溶液 PH，也影响沉积方法。可以制造 DNF 和其他亚硝酸钛涂层基材，如硅硅、传统玻璃、ITO 玻璃和 FDO 玻璃，用于各种应用。处理样品时必须小心，因为如果金DNF足够生病，很容易从亚硝酸盐钛硅基材中去除金DNA。使用含有氟化氢的缓冲氧化物蚀刻时，请记得佩戴个人防护装备。
