【摘要】 |
|
Titanate nanotubes and their derivates, Pd-loaded and Co2+, Zn2+, Cu2+, and Ag+ ion-exchanged titanate nanotubes, were respectively prepared and characterized by XRD, HR-TEM, and EDS. Their hydrogen storage properties were investigated, and the results revealed that the derivated titanate nanotubes had better hydrogen storage characters. Pd-loaded titanate nanotubes exhibited the highest hydrogen storage capacity of 1.03 wt%, which is three times higher than that of raw titanate nanotubes. The ion-exchanged titanate nanotubes also showed enhanced capacity. Especially, Co-TiNT reached a storage capacity of 0.80 wt%. The reason why hydrogen storage capacity was enhanced in titanate nanotubes was a pilot study. These results indicated that oxide nanotubes provided some new opportunities for hydrogen energy applications. |
