摘要：
The preparation of WO3 nanorods by double-walled carbon nanotube (DWCNT) template was investigated in this study. Owing to that the prepared H2WO4 can be isolated by the homogenously dispersed DWCNT bundles and secondary accumulation can be avoided effectively, the growth of H2WO4 can be restrained, and H2WO4 nanorods with diameter of 10-50 nm can be prepared. After calcination of the prepared DWCNT/H2WO4 composite in oxygen, WO3 nanorods with diameter of 10-100 nm and high specific surface area of 16.4 m(2).g(-1) can be obtained. It is concluded that the DWCNTs play an important role in the effective mediation of the morphology and size of nano-WO3.
