我们讨论了个别石墨纳米杯的使用了一系列的技术,包括化学气相沉积,氧化和探针尖端的超声处理获得的合成。柠檬酸钠还原氯金酸
以下实验的总体目标是合成从氮、倾倒的碳纳米管中分离的单个亲水性石墨纳米杯,并用金纳米颗粒作为软木塞对其进行功能化。首先通过化学气相沉积合成由堆叠纳米杯组成的氮掺杂碳纳米管来实现。作为第二步,堆叠的纳米杯有时会用强酸性氧化和探针尖端处理,从而有效地将单个纳米杯从其堆叠中隔离出来。
接下来,通过在分离的纳米杯存在下通过柠檬酸钠还原氯甲酸来合成金纳米颗粒,以便在纳米杯的开口处塞住纳米杯,获得结果显示金纳米颗粒有效地塞住了纳米杯的开口基于透射电子显微镜和紫外可见光谱表征。当我们分析氮气掺杂碳管的透射电子显微镜图像时,我们首先想到了分离和塞住碳管杯的想法,并注意到它们由单独的杯状段组成。这种方法可以帮助回答纳米科学和纳米技术领域的关键问题,例如纳米结构的控制、形状和功能特性。
