The surface microstructure of prepared ZnO@rGO nanocomposite was analyzed by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, Raman spectroscopy, and X-ray photo electron spectroscopy. Different characterization analysis indicates that the ZnO NPs in the nanocomposite were dispersed on the surfaces of rGO nanosheets (NSs). Raman spectra reveal the structural defects level of rGO NSs was 0.78, while it was increased to 1.66 for ZnO@rGO nanocomposites. The synthesized ZnO@rGO nanocomposite exhibits specific capacitance of 102.4 F/g at the scan rate of 30 mV/s and shows good cyclic stability of 82.5% for 3000 cycles at high scan rate 100 mV/s.

Traditional wastewater treatment plants are insufficient and cannot meet the basic standards of water quality at reasonable cost or processing time. In this paper we report the preparation, characterization and multiple applications of an efficient photocatalytic nanocomposite (CoxNi1−xFe2O4; x = 0.9/SiO2/TiO2/C-dots) synthesized by a layer-by-layer method. Then, the photocatalytic capabilities of the synthesized nanocomposite were extensively-studied against aqueous solutions of chloramine-T trihydrate. In addition, reaction kinetics, degradation mechanism and various parameters affecting the photocatalytic efficiency (nanocomposite dose, chloramine-T initial concentration, and reaction pH) were analyzed in detail. Further, the antimicrobial activities of the prepared nanocomposite were tested and the effect of UV-activation on the antimicrobial abilities of the prepared na...

The microwave irradiation assisted synthesized HOrGO filled with NiO/Co 3 O 4 NPs (HOrGO/ TMOs) hybrids exhibits high specific capacitance with improved cycling stability as excellent electrode materials for supercapacitors (SCs). The HOrGO NSs contains high surface area (~570 m 2 g −1) due to highly exfoliated nanostructure comprising open edges enriched morphology. In HOrGO/TMOs hybrids, the several micron-sized (~100 μm) open edges of HOrGO NSs holds the NiO/Co 3 O 4 NPs with finely separated thin few-layer graphene NSs. The structural/ morphological analysis of synthesized HOrGO NSs and HOrGO/TMOs hybrids were extensively characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), Raman spectra, thermogravimetric analysis (TGA) and Brunauer-Emmett-Teller (BET) surface area. The HOrGO/TMOs hybrids deliver high specific capacitance of 910 F g −1 and high robust cycling stability with capacitance retention as 89.9% after continuous 2000 cycles. The proposed mechanism explain the microwave irradiation assisted formation of HOrGO/TMOs hybrids and provides a general and low-cost approach to synthesized high quality graphene hybrids materials for SCs application.

Research paper thumbnail of Superior performance of Ni(OH)2-ErGO@ NF electrode materials as pseudocapacitance using electrochemical deposition via two simple successive steps

Journal of Energy Storage, 2020

The adopted three-electrode electrochemical system via a two-step process for the synthesis of Ni(OH)2-ErGO@NF was fast and cost effective. First, 2D nanosheets of ErGO were deposited on NF by potential square wave technique. Second, Ni(OH)2 nanoparticles were deposited on the surface of 2D nanosheets ErGO by potentiostat. The electrochemical behavior of the Ni(OH)2-ErGO@NF electrode was measured in 1 M KOH and revealed an impressive supercapacitive performance, with high specific capacitance of 3138 F/g at scan rate 20 mV/s. The synthesized Ni(OH)2-ErGO@NF exhibited excellent cyclic stability, with capacitance retention of 88.6% after 3000 cycles at a scan rate 50 mV/s. The enhanced electrochemical performance of SCs was attributed to the superior conductivity of ErGO NSs, which facilitated the transfer of charges and the diffusion of KOH electrolyte, making it is a promising candidate for SCs electrodes. This synthesis provides an appropriate approach for preparing other kinds of metal hydroxides with rGO for improved SCs electrode performance.

The Pd-E-ErGO hybrids material was successfully prepared by facile and one-pot in-situ electrochemical reduction and deposition using water as solvent in which palladium nanoparticles (Pd NPs) were uniformly embedded inside 2D-nanosheets of ErGO. During electrochemical reduction, graphene oxide nanosheets were reduced into ErGO NSs and PdCl 2 ionized to form Pd 2+ which attracted to the negative oxygen containing functional groups of ErGO NSs then reduced to form Pd NPs which embedded completely between ErGO NSs structure. The surface/ structural morphology of Pd-E-ErGO hybrids was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), energy-dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. The proportions of elements present in hybrids were determined by EDS and thermogravimetric analysis (TGA). As an application, the synthesized Pd-E-ErGO hybrids revealed enhanced electrochemical performance as high specific capacitance with excellent cycling stability which was very significant for electrochemical SCs. The Pd-E-ErGO hybrids electrode fulfills an approving specific capacitance value of 1524.7 F/g at a scan rate of 20 mV/s and improved cycling stability of 92.1% capacitance retention after 2000 cycles in the three-electrode setup. The electrochemical synthesis of Pd-embedded-graphene derivatives structure as well as improved electrochemical performance for SCs opens up a new idea to prepare electrode materials.
