ABSTRACTMo doped vanadium oxide nanotubes (VONT) were formed via a rheological phase reaction followed by self-assembling process and were heated at 400 □ in an inert atmosphere. The nanotubes were characterized by SEM, HRTEM, XRD, FTIR, electrochemical investigation, etc. In contrast to the undoped VONTs, the interlayer distance between oxide layers in the (V0.99Mo0.01)xONTs increases owing to replacement of some V in nanotubes by Mo with a larger ionic radius, resulting in a shorten diffusion length of Li ions and an improved electrochemical performance. The electrochemical performance of (V0.99Mo0.01)xONTs is further enhanced by removing the residual organic template by heating in an inert atmosphere.

The pore, crystal structure, and electrochemical performance of mesoporous MnO2prepared by silica sol template method as electrode material for supercapacitor were investigated in this work. It is found that the crystal structure of nonporous and mesoporous MnO2is confirmed to beβ-MnO2and the crystallinity of mesoporous MnO2decreases due to the formation of mesopore. The results of electrochemical performance show that the specific capacitances of the sample prepared by using 20 g of Mn(NO3)2solution and 40 g of silica sol (named MMO-4) at the scan rate of 5 mV/s are the highest (163.2 F/g), in comparison with 19.3 F/g of that of the sample of blank, suggesting the important role of pore-forming using silica sol as template. As the potential scan rate is raised to 200 mV/s, the specific capacitances of the sample of blank and MMO-4 are 12.2 F/g and 21.6 F/g, respectively. The great improvement of specific capacitance is probably due to the enlarged activated surface area after template is added.
