Carbon nanotube (CNT)/maleic acid anhydride (MAH)-grafted polypropylene (PP) composites were prepared by in situ grafting method. Infrared spectroscopy showed that the CNTs were linked to PP by MAH grafting. The microstructures and calorimetry analysis indicated that the crystallization behaviors of...

The substrate pre-treatment plays a key role in obtaining hollow-cored carbon nanotubes (CNTs) and solidcored carbon nanofibers (CNFs) from flames. This paper introduces a simply and high-efficient process by coating a NiSO4 or FeSO4 layer on the substrate as catalyst precursors. Comparing with the ...

CO2 is a major component of the greenhouse gases, which causes the global warming. To reduce CO2 gas, high activity nanosized Ni+2 substituted Fe2TiO5 samples were synthesized by conventional ceramic method. The effect of the composition of the synthesized ferrite on the H2-reduction and CO2-catalyt...

A nanocomposite of nickel oxide/carbon nanotubes was prepared through a simple chemical precipitation followed by thermal annealing. The electrochemical capacitance of this electrode material was studied. When the mass fraction of CNTs (carbon nanotubes) in NiO/CNT composites increases, the electric...

We present a brief review about recent results regarding carbon nanotube (CNT)-based chemical and biomole-cular sensors. For the fabrication of CNT-based sensors, devices containing CNT channels between two metal electrodes are first fabricated usually via chemical vapor deposition (CVD) or “surface...

利用爆炸辅助的化学气相沉积方法,以一系列稀土元素作为催化剂合成了多壁碳纳米管(MWCNTs).通过能量色散X射线谱、选区X-射线电子衍射谱和粉末X-射线衍射数据表明,催化剂是以氧化物形式存在MWCNTs外,这不同于传统的以金属或碳化物存在.结合中间体结构,结果显示,MWCNTs的形成遵循颗粒-线-管...
