Starch based carbon nanotubes-iron oxide (CNT-IO) and carbon nanotubes-zirconium oxide (CNT-ZO) nanocomposites (NCs) were fabricated using facile microwave irradiation technique from different...

碳纳米管是晶形碳的一种同位素异形体，从结构上为蜂巢状的一维纳米空心管，其中 C-C 原子以 sp2杂化构成共价键。 根据碳纳米管的管壁数，可分为 单壁碳纳米管 （SWCNT）和 多壁碳纳米管 （MWCNT），而根据碳纳米管的结构特征又可分为 扶手椅形 、 锯齿形 和 螺旋型 三种，其中螺旋型碳纳米管具有手性，而锯齿形和扶手椅型碳纳米管没有手性。 图1. 单壁碳纳米管和多壁碳纳米管的结构示意图. 碳纳米管重量轻，六边形结构连接完美，具有许多优异的力学性能、导电性 …

2015年2月1日 · XRD profile of a SWCNT synthesized by arc discharge method (Ni/Y/C 0.5-0.5-99 at.%) (Top Curve). Theoretical diffraction profile calculated for tubes with average diameter 1.34 nm and average ...

2001年8月17日 · X-ray diffraction (XRD) studies were performed on carbon nanotubes (CNTs) with various alignment degrees synthesized by catalytic pyrolysis of ferrocene and xylene. A qualitative relationship between the peak intensities of the XRD patterns and the degrees of nanotube alignments was established.

2009年6月24日 · We develop an efficient algorithm and a novel recurrence relation for computing the Debye function of carbon nanotubes. This allows the computation of the XRD profile of CNTs for arbitrary lengths in times which scales linearly with the tube length.

2024年4月11日 · 图2中的X射线衍射（XRD）对MnO2@CNTs和MnO2进行了进一步的物相分析。 除碳峰外MnO2@CNTs的特征峰与纯净的ε-MnO2相非常吻合，这表明CC中顺利地负载了ε-MnO2而没有其他杂质。

3 天之前 · The XRD patterns of nanocomposites TiO 2 /CNT showed XRD peaks at 27.7°, 44.5°, 55.1°, and 61.5° 2θ, which confirms the hexagonal lattice structure . The broad peak was observed in the composite TiO 2 /CNT with higher crystallinity but this peak split into two peaks by incorporation of GO into the TiO 2 /CNT composite.

The XRD pattern of CNT is a classical representation of CNT, as reported in many studies [44]. The crystal system of CNT is hexagonal with space group P63mc with a = b = 2.47 Å and c = 6.79...

2019年7月5日 · In our chapter, X-ray families were used for quantification and qualification of carbon nanotubes. XRD, XRF, EDX, and XPS were used in this chapter with many synthesized CNTs to show the abilities for evaluating the purifies which are very important in applications.

2020年3月17日 · Multi walled carbon nanotubes (MWCNTs) were decorated by activated carbon nanoparticles of resorcinol-formaldehyde aerogels. Carbon nanospheres and MWCNTs were mixed by equal mass ratios for...
