A semi-flexible binder-free graphitic carbon nitride(g-CN) intercalated polypyrrole(PPy) nanocomposite thin film was prepared via hybrid electrospray technique. A homogeneous thin film was achieved by the controlled spray process. A deposited thin film illustrated the amorphous nature of composite with high surface purity and good chemical composition. The surface analysis confirmed the smoother surface with well-defined distinct phases of g-CNand PPy matrix in the composite thin film. The electrochemical studies exhibited that a maximum areal capacity of the thin film was achieved to be 289.6 mF/cm~2 at a current density of 0.4 mA/cm~2,which is higher than that of pristine PPy(194.8 mF/cm~2). The heterostructure electrode illustrated that the life cycles of 99% could be up to 10,000 cycles with low resistance due to the synergetic effect of g-CNand PPy matrix with strong material adhesion(hybrid spray process) on the surface. A binder-free heterostructure thin film will play a significant role in the energy storage application.

Sonochemical synthesis of nanostructured nickel hydroxide as an electrode material for improved electrochemical energy storage application

Progress in Natural Science:Materials International 2017年第4期27卷 416-423页

A facile and fast approach for the synthesis of a nanostructured nickel hydroxide(Ni（OH）;) via sonochemical technique is reported in the present study. The X-ray diffraction results confirmed that the synthesized Ni（OH）;was oriented in β-phase of hexagonal brucite structure. The nanostructured Ni（OH）;electrode exhibited the maximum specific capacitance of 1256 F/g at a current density of 200 mA/g in 1 M KOH;. Ni（OH）;electrodes exhibited the pseudocapacitive behavior due to the presence of redox reaction. It also exhibited long-term cyclic stability of 85% after 2000 cycles, suggesting that the nanostructured Ni（OH）;electrode will play a promising role for high performance supercapacitor application.
