Application of a one dimensional Co-MOP wires on supercapacitors
Herein, we designed and prepared a one-dimensional (1-D) cobalt-based metal organic coordination polymer (2,4-pdc-Co) by hydrothermal method. 2,4-pdc-Co has the molecular formula of Co 4 (H 2 O) 10 (2,4-pdc) 4 and possesses orthorhombic symmetry Pna 2 1 space group. In the same synthesis method, we added urea as a template. On the premise of maintaining this 1-D microstructure, we modified the block-shape 2,4-pdc-Co into a 1-D wire (2,4-pdc-Co-W). As an electrode material for supercapacitors, compared with 2,4-pdc-Co, the modified 2,4-pdc-Co-W shows better electrochemical performance. The specific capacitance of the optimized electrode material can reach 325 F g -1 at 1 A g −1 . 2,4-pdc-Co-W is also assembled with activated carbon to form a battery-type hybrid supercapacitor. As the positive material for the device, an assembled hybridcapacitor delivers an energy density of 17.7 Wh kg −1 at power density of 400 W kg −1 .
