Synthesis and Hydrogen Storage Capacity of SiC Nanotube

摘要：

　　Hollow nanostructures have important applications in the field of gas adsorption,separation and storage due to their large specific surface areas.Silicon carbide nanotubes (SiCNTs) are one kind of such materials.In this paper,SiCNTs were synthesized from multiwalled carbon nanotubes (MWCNTs) via chemical vapor reaction (CVR) and purification.The SiCNTs were characterized by XRD,SEM and TEM.The results revealed that C-SiC nanotubes were obtained after CVR and most carbon were removed after purification with some traces retained inside SiCNTs.Hydrogen storage capacities measurements indicated that SiCNTs are superior to MWCNTs.
