Abstract
Abstract Cu3V2O7(OH)2·2H2O (CVO) nanoribbons are fabricated through a facile hydrothermal approach, showing a layered structure and multiwater framework proven by TEM, XRD, and FT-IR measurements. The CVO nanoribbon electrode exhibits a specific capacitance of 121 F g−1 at a current density of 500 mA g−1 in 1.0 M KNO3. While PANI materials are both coated on and intercalated into the CVO, the specific capacitance is greatly improved to 197 F g−1.
