Abstract
It relates to a type of catalysts for preparation of chirality-selective and conductivity-selective single-walled carbon nanotubes. The catalysts have chemical compositions of ABy, wherein A is the metal tungsten (W), B stands for one or more metals selected from a group consisting of the transition metals manganese, iron, cobalt, copper, zinc, chromium, vanadium, rhodium, ruthenium, palladium, platinum, gold, silver, osmium, iridium, and the lanthanide rare earth metals, and y is in the range of 0.01-20.0. This catalyst can be used to catalyze the growth of single-walled carbon nanotubes with desired chirality and conductivity.
