Enhancement of the Supercapacitive Performance of Cobalt-tin-cyanate Layered Structures through Conversion from 2D Materials to 1D Nanofibers

Rational design of the micro-nanomorphology is highly desired for metal hydroxides to achieve overall high-performance electrodes supercapacitor and energy storage applications. Here, in current study, we have succeeded controlling morphology Sn/Co nanolayered structures obtain plate nanofibrous morphologies. Additionally, nanostructures could be transformed plate-nanofibrous In this trend, dual anions such as cyanate nitrate are applied intercalate among nanolayers cobalt-tin act building blocks or pillars, producing a series structures. By repulsion forces intercalated anions, curled converted nanofibers. This conversion was confirmed by scanning electron microscopy. addition, intercalation reactions were indicated X-ray diffraction, thermal analyses Fourier-transform infrared spectroscopy. The electrochemical supercapacitive behavior different HDS LDH, plate, Plate-nanofiber has been investigated three assembly electrode system. results suggested that nanofiber LDH exhibited better specific capacitance performance than other two enhanced (658 Fg−1) excellent cyclic stability (89%) nanofibers attributed synergistic effects between electric double layer capacitive character tin pseudocapacitance nature cobalt.
