Reducing and Uniforming the Co(3)O(4) Particle Size by Sulfonated Graphenal Polymers for Electrochemical Applications

A novel two-dimensional (2D) nanomaterial, namely sulfonated graphenal polymer (SGP), is used to tune the hydrothermal growth of Co(3)O(4) nanoparticles. SGP provides abundant nucleation sites to grow Co(3)O(4) nanoparticles and effectively reduces the particle size and dimension. As a result, with...

description A novel two-dimensional (2D) nanomaterial, namely sulfonated graphenal polymer (SGP), is used to tune the hydrothermal growth of Co(3)O(4) nanoparticles. SGP provides abundant nucleation sites to grow Co(3)O(4) nanoparticles and effectively reduces the particle size and dimension. As a result, with considering the improved size uniformity of Co(3)O(4) and the tight wrapping of SGP around Co(3)O(4) as well, the Co(3)O(4)/SGP hybrid electrode exhibits a high specific electrochemical capacitance of 234.28 F/g at a current density of 0.2 A/g, 237% higher than that of the pure Co(3)O(4) electrode. By using the hybrid as the anode of an all-solid-state asymmetric supercapacitor, the capacitance can be well maintained up to 93% after 5000 cycles even at 2 A/g.
