摘要: 3D bundle-shaped multi-walled carbon nanotubes and preparation method, includes the following steps: uniformly mixing bi-component alloy catalyst and transition metal in an inert gas environment in order to obtain a three-component nano-intermetallic alloy catalyst; disposing the intermetallic catalyst on the substrate; allowing hydrogen to flow through the substrate, and heating the substrate to a first temperature, and using the hydrogen to undergo a reduction of the intermetallic catalyst at the first temperature; applying a protective gas and a carbon source gas, heating the substrate to a second temperature, undergoing a reaction at the second temperature to generate the 3D bundle-shaped multi-walled carbon nanotubes, and collecting the 3D bundle-shaped multi-walled carbon nanotubes after annealing; wherein the second temperature is greater than or equal to the first temperature; a working electrode includes conductive drain material, a conductive bonding gent and a plurality of 3D bundle-shaped multi-walled carbon nanotubes.

摘要: A method for detecting a gas sample includes the following steps of: providing a carbon aerogel sleeve; introducing a gas sample to the carbon aerogel sleeve, and then sequentially extracting, concentrating, activating, and re-concentrating the gas sample adsorbed by the carbon aerogel and detecting a concentration of the re-concentrated gas sample by a gas chromatograph-mass spectrometer (GC-MS); and extracting the carbon aerogel for several hours with reflux in a dichloromethane solvent and a n-hexane solvent several times per hour to remove the residual gas sample, and then drying the extracted carbon aerogel for reuse, wherein the dichloromethane solvent and the n-hexane solvent are at a volume ratio of 0.001-1000.
