“…12 These properties will eventually lead to improved electrochemical performance of CDs-based nanocomposites. Metal oxides (MOs) 13 and conducting polymers (CPs) 14 generally used for pseudo capacitors owing to their higher electrochemical (redox) activity, lower cost, and environment friendly nature. 15 Further, composites which comprise of both EDLC and pseudocapacitor electrode materials such as rGO-ZnO, 16 rGO-PPY, 17 and Graphene-PANI 18 are utilized for hybrid supercapacitors.…”

Summary The increasing thrust lies in developing a better electrode material for supercapacitor applications. Carbon and metal oxide‐based nanocomposites are the latest trend in this research area. In the present work, we are proposing the synthesis of simple, eco‐friendly and cost‐effective reduced graphene oxide (rGO), naturally derived carbon dots (CDs), and zinc oxide (ZnO)‐based rZD ternary nanocomposites. These nanocomposites have been synthesized using eco‐friendly and accessible hydrothermal method at three different temperatures (i.e., 300, 400, and 500°C) and accordingly named as rZD300, rZD400, and rZD500. Further, the morphological (scanning electron microscopy and transmission electron microscopy) characterization studies predicted that ZnO and CDs were attached on to the rGO nanosheets to form the rhinestone sheet like structures. In addition, the crystalline and structural properties have been examined using X‐ray diffraction, Raman, X‐ray Photoelectron Spectroscopy, and X‐ray Absorption Spectroscopy. The electrochemical studies (cyclic voltammetry, galvanostatic charge‐discharge, and electrochemical impedance spectroscopic) predicted that highest capacitance achieved was 796 F/g using 2 M H2SO4 electrolytic solution for rZD500 nanocomposite. Finally, 1.5 V prototype flexible Supercapacitors (FSC) have been also fabricated using carbon cloth substrate for rZD500nanocomposite.

“…For getting superior performance in supercapacitors, the type and composition of an electrode is very important. The electrode materials, such, as, metal oxides [5,6], doped metal oxides [7][8][9], carbon-based materials [10,11], conducting polymers [12,13], and nanocomposite [14,15] based materials were used in supercapacitors. NiO-based electrode materials were considered as one of the best materials for supercapacitor applications for the past one or two decades.…”

Mn doped NiO nanostructured materials with composition Ni 1-x Mn x O 1-δ (where x = 0.01, 0.03, 0.05, 0.07, 0.09) (MNO) were prepared by simple facile chemical synthesis route. The structural, particulate and microstructural characteristics of the Mn-doped NiO nanostructures were studied by studied by XRD, FTIR, particle size analysis, EDAX, SEM and HRTEM techniques. The XRD peaks of all the materials were indexed to the face-centred cubic (FCC) crystalline structure. FTIR spectra revealed the presence of NiO bending vibration mode between 432.07 to 492.83 cm-1. Particle size patterns and SEM photographs confirmed the presence of nanosized grains apart from few bigger sized grains. The diameter of grains was mostly found to be in the range of 30.04 to 591.16 nm. Presence of appropriate composition of elements was confirmed by EDAX data. Polycrystalline behaviour of Ni 0.95 Mn 0.05 O 1-δ was exhibited by HRTEM data. The electrochemical phenomena of Ni 1-x Mn x O 1-δ were studied by cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance measurements in 6 M KOH aqueous solution. Among the samples studied, Ni 0.95 Mn 0.05 O 1-δ electrode exhibited maximum specific capacitance of 369.6 Fg-1 at a current density of 0.5 Ag-1. From the characterization data, Mn-doped NiO nanostructures appear to be the good electrode materials for electrochemical supercapacitor applications.
