| ABSTRACT |
|
High-porosity nanostructured materials are in high demand for use in electrochemical supercapacitor applications due to their immense specific surface areas, which allow for significant energy storage capacity. Using Ti(CH3COO)2⋅2H2O and nitrate salts of dopants such as Cerium, Samarium, Holmium, and Ytterbium as precursors, we synthesized mixed metal-doped TiO22-1 at a current density of 2.0 A g-1. The enhanced electrochemical performance of the optimized Co-doped TiO222 nanostructures have a wide spectrum of potential electrochemical applications. |
