Facile Synthesis of Polyindole/Ni Zn FeO ( = 0, 0.5, 1) Nanocomposites and Their Enhanced Microwave Absorption and Shielding Properties.

The present work reports the fabrication of polyindole (PIN)/Ni Zn FeO ( = 0, 0.5, 1) nanocomposites as efficient electromagnetic wave absorbers by a facile in situ emulsion polymerization method for the first time. The samples were characterized through Fourier transform infrared spectroscopy, UV-vis spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, high-resolution transmission electron microscopy, and vibrating sample magnetometry.

g-CN/CuO and g-CN/CoO nanohybrid structures as efficient electrode materials in symmetric supercapacitors.

Metal oxide dispersed graphitic carbon nitride hybrid nanocomposites (g-CN/CuO and g-CN/CoO) were prepared a direct precipitation method. The materials were used as an electrode material in symmetric supercapacitors. The g-CN/CoO electrode based device exhibited a specific capacitance of 201 F g which is substantially higher than those using g-CN/CuO (95 F g) and bare g-CN electrodes (72 F g).
