THE PURIFYING OF CARBON NANOTUBES OXIDATION METHOD BY USE OF K 2Cr 2O 7
Source abstract
Abstract
A new method of carbon nanotubes purification is introduced,by which K 2Cr 2O 7 was taken as the oxidation agent instead of air.The influences of temperature,sulfuric acid concentration and reaction time on the reaction was studied.The optimum condition was obtained as follow:temperature 140℃,time 2 h.the concentration of sulfuric acid 1∶1 (ratio of volume),and H 2SO 4∶K 2Cr 2O 7=6∶1 (ratio of mol),the mechanism of purification was also discussed.
