Diamond formation on carbon/carbon composite

A carbon/carbon composite was used as substrate for low-pressure diamond deposition. To enhanced diamond nucleation on carbon/carbon composites, a total of ten surface preparation methods have been investigated. These methods involved the use of atomic hydrogen etching, mechanical polishing, sonication, or coating. Diamond nucleation was found to occur on either the defects of the carbon/carbon composite substrates or diamond particulate left on the substrates. The defects were created primarily by atomic hydrogen etching during the coating process. Seeding with diamond powders was performed by dip coating, sonication, or spray-coating processes. It was found that these seeding processes resulted in excellent nucleation of diamond.

活性炭纤维(ACF)吸附二硫化碳(CS2)的研究

研究了商用活性炭纤维(Activated carbonf fiber-ACF)对二硫化碳(Carbon disulfide-CS2)的吸附件能,并与活性炭(Activated carbon-AC)、沸石吸附CS2的性能做了对比.重点考察了CS2浓度、吸附气流量、湿度和ACF含水量对CS2在ACF上吸附性能的影响.结果表明:相对于AC、沸石,ACF对CS2的吸附快、吸附率高,达46.5%;CS2浓度、吸附气流量增加,穿透点前移;湿度和含水量上升会明显降低ACF对CS2的吸附性能,当湿度升至65%时,吸附时间缩短28.6%;当含水量为质量分数45%时,穿透时间提前42.9%;当含水量增至质量分数60%时,CS2迅速穿透,ACF几乎不能再吸附CS2.     

碳纤维衬底上定向碳纳米片阵列的制备

以乙炔(C2H2)为碳源,N2为载气,二茂铁为催化前驱物,采用浮动催化法,在碳纤维衬底上制备了垂直定向的碳纳米片阵列.利用SEM,EDX和Raman光谱对所得产物进行了表征.结果表明经十二烷基磺酸钠(SDS)和二茂铁的丙酮溶液煮沸和浸泡处理后的碳纤维表面所生长的碳纳米片长度约为600 nm,宽度约为50 nm.Raman光谱分析表明所制备的碳纳米片为石墨结构.碳纤维的预处理不仅活化了表面,而且避免了催化剂向其内部的渗透和吸收.基于以上结果,碳纤维/碳纳米片在场发射领域很可能有重要的应用.

Effect of carbon nanofibers on the infiltration and thermal conductivity of carbon/carbon composites

Preforms containing 0, 5, 10, 15 and 20 wt.% carbon nanofibers (CNFs) were fabricated by spreading layers of carbon cloth, and infiltrated using the electrified preform heating chemical vapor infiltration method (ECVI) under atmospheric pressure. Initial thermal gradients were determined. Resistivity and density evolutions with infiltration time have been recorded. Scanning electron microscopy, polarized light micrograph and X-ray diffraction technique were used to analyze the experiment results. The results showed that the infiltration rate increased with the rising of CNF content, and after 120 h of infiltration, the density was the highest when the CNF content was 5 wt.%, but the composite could not be densified efficiently as the CNF content ranged from 10 wt.% to 20 wt.%. CNF-reinforced C/C composites have enhanced thermal conductivity, the values at 5 wt.% were increased by nearly 5.5-24.1% in the X-Y direction and 153.8-251.3% in the Z direction compared to those with no CNFs. When the additive content was increased to 20 wt.%, due to the holes and cavities in the CNF web and between carbon cloth and matrix, the thermal conductivities in the X-Y and Z directions decreased from their maximum values at 5 wt.%.     

Oxygen reduction activity of carbon nitride supported on carbon nanotubes

Fuel cells offer an alternative to burning fossil fuels, but use platinum as a catalyst which is expensive and scarce. Cheap, alternative catalysts could enable fuel cells to become serious contenders in the green energy sector. One promising class of catalyst for electrochemical oxygen reduction is iron-containing, nanostructured, nitrogen-doped carbon. The catalytic activity of such N-doped carbons has improved vastly over the years bringing industrial applications ever closer. Stoichiometric carbon nitride powder has only been observed in recent years. It has nitrogen content up to 57% and as such is an extremely interesting material to work with. The electrochemical activity of carbon nitride has already been explored, confirming that iron is not a necessary ingredient for 4-electron oxygen reduction. Here, we synthesize carbon nitride on a carbon nanotube support and subject it to high temperature treatment in an effort to increase the surface area and conductivity. The results lend insight into the mechanism of oxygen reduction and show the potential for carbon nanotube-supported carbon nitride to be used as a catalyst to replace platinum in fuel cells.

Controlling electron-beam-induced carbon deposition on carbon nanotubes by Joule heating

Electron-beam-induced deposition (EBID) of carbon on the surface of carbon nanotubes was well controlled by passing different electrical currents through the nanotubes. The control is due to Joule heating and the temperature of the carbon nanotubes was estimated. The deposition rate was found to increase and then decrease with the temperature and was maximized at about 310?K and approached zero at about 400?K. The method can be used to control the deposition rate of EBID in nanowelding and nanofabrication and to eliminate amorphous carbon contamination in in situ study of nanostructures.
