摘要:A novel route was developed to synthesize amorphous carbon nanotubes (a-CNTs) from organic carbon using V2O5 and glucose solution as the starting materials. The annealing process can stabilize organic carbon shells, leading to the successful formation of a-CNTs, which is the crucial step for preparing a-CNTs. The as-obtained a-CNTs have uniform diameters with outer diameter ranging from 150 to 250-nm and inner diameter about 30 nm on average, and their length is up to several micrometers. The carbon in the as-synthesized a-CNTs is completely amorphous, and the as-prepared a-CNTs are a kind of hydrogenated a-CNTs containing both sp(3)- and sp(2) carbons. Furthermore, the as-prepared a-CNTs have good thermal stability and oxidation resistance below 305 degrees C in air.
