摘要:
Disclosed are a carbon nanotube aggregate and a method for forming a carbon nanotube aggregate. An aggregate can be obtained by fluorinating the surfaces of carbon nanotubes. The method for forming a carbon nanotube aggregate is characterized by comprising a step for firing a plurality of fluorinated carbon nanotubes.
摘要:
A carbon nanotube aggregate and a method for forming a carbon nanotube aggregate are provided. The carbon nanotube aggregate can be formed by treating carbon nanotubes with fluorine gas and sintering the resulting fluorinated carbon nanotubes. A carbon nanotube aggregate can be formed which does not contain a binder or resin matrix.

Provided is a method for purifying a quaternary alkyl ammonium salt enabling the obtainment of a particulate quaternary alkyl ammonium salt having a low water content at a high yield which is suitably used as an electrolyte in an electrolytic solution. The method for the purification of a quaternary alkyl ammonium salt comprises dispersing a quaternary alkyl ammonium salt to be purified into an organic solvent to allow it to form a suspension there. The alkyl groups constituting the quaternary alkyl ammonium salt have 1 to 5 carbon atoms each. The quaternary alkyl ammonium salt to be purified is dispersed into the organic solvent to make a suspension, and then the particles are washed with an alcohol solvent.

摘要:
The invention aims at providing a platinum black material, without using an expensive and rare material, which is excellent in CO poisoning inhibiting effect, H2S poisoning inhibiting effect, SO4 poisoning inhibiting effect and HCHO poisoning inhibiting effect, and a method for fluorinating platinum black. The platinum black material is characterized by fluorine adsorbed on its surface. The method for fluorinating platinum black is characterized by allowing platinum black to stand in a mixed gas atmosphere of n inert gas and fluorine in a low-pressure chamber to make fluorine adsorbed on the surface of the platinum black.
