Nanoscale Energetics with Carbon Nanotubes

摘要: Single wall carbon nanotubes (SWNTs) with diameters below 1 nm prepared by chemical vapor deposition (CVD), and of 1.3 higher laser ablation carbon-arc techniques, were electrochemically functionalized hydrogen nitro groups, chemically derivatized 4-nitroaniline. Hydrogen adsorption on SWNTs was carried out in the presence or absence electrodeposited catalytic nanoparticles magnesium. deposited Teflon-coated membranes vacuum filtration lifted off as free-standing nanopaper, used electrodes for electrochemical functionalization reactions. uptake characterized micro-Raman spectroscopy, thermogravimetry thermopower measurements. Electrochemically-induced −NO 2 groups metallic, laser-synthesized clearly detected Raman spectroscopy. Chemical achieved CVD-produced acidification to form −COOH followed reaction thionyl chloride then Photoacoustic effects that are likely be precursors photo-induced initiation energetic reactions, observed occur at varying intensities these materials experiments using a pulsed Nd-YAG emitting 532 nm.
