Synthesis of carbon nanotube heterojunctions from the decomposition of ethanol

A new bimetallic catalyst of nickel-copper doped with praseodymium was used in the decomposition of ethanol. Results obtained showed the formation of a high density of carbon nanotube heterojunctions with the nanotubes having diameters ranging from 10 to 40 nm. Field emission scanning electron micro...
