摘要
Abstract
The surfaces of acid-functionalized carbon nanotubes(CNTs)were coated by TiO2 produced by the hydrolysis of TiC14,which was converted into Ti through temperature-programmed reduction(TPR)equipment.SEM,TEM,XRD,and EDAX analyses were used to characterize the primary CNTs,as-prepared TiO2-coated CNTs and the Ti-coated CNTs.It was found that after the functionalization of CNTs by ultrasonic-assisted acid treatment,TiO2 was successfully coated onto the CNTs,which was reduced in TPR under H2/Ar flow at 850℃ to metal Ti.The Ti transition layer is important for the formation of composites of CNTs with other metals.关键词
