Abstract

In this work, two dimensional nanostructures like Zinc phthalocyanine (ZnPc) nanoflakes are synthesized by low temperature surfactant assisted hydrothermal route. ZnPc nanoflakes exhibit areal capacitance 486.4 mF/cm2 at current density 2.4 mA/cm2 and also very good cycling stability of ~96% capacitance retention and ~99% coulombic efficiency even after 2000 cycles. These results promote ZnPc nanoflakes as the electrode material of supercapacitor applications.
