One-step synthesis of Ni3S2 nanorod@Ni(OH)2 nanosheet core-shell nanostructures on a three-dimensional graphene network for high-performance supercapacitors
A three-dimensional graphene network (3DGN) grown on nickel foam is an excellent template for the synthesis of graphene-based composite electrodes for use in supercapacitors. Ni(OH)2nanosheets coated onto single-crystal ...
A simple process to prepare nitrogen-modified few-layer graphene for a supercapacitor electrode
We report a simple approach to prepare the nitrogen-modified few-layer graphene (FLG) directly from graphite flakes. With the aid of melamine, graphite flakes can be directly ultrasonicated into FLG in acetone. The subsequent ...
Three-dimensional graphene network composites for detection of hydrogen peroxide
A three-dimensional graphene network (3DGN) prepared by CVD is used as a template to synthesize various composites. These composites are further used as electrodes for electrochemical sensors, which exhibit a low detection ...
Controlled synthesis of manganese oxyhydroxide nanotubes : implications for high-efficiency supercapacitors
Successful attempts have been made to control the synthesis of tubular MnOOH with nanodimensions on high electronic conductivity graphite felt (GF) to be used as a flexible supercapacitor electrode. As a fundamental study, ...
Preparation of MoS2-coated three-dimensional graphene networks for high-performance anode material in lithium-ion batteries
A novel composite, MoS2-coated three-dimensional graphene network (3DGN), referred to as MoS2/3DGN, is synthesized by a facile CVD method. The 3DGN, composed of interconnected graphene sheets, not only serves as template ...
MS2 (M = Co and Ni) hollow spheres with tunable Interiors for high-performance supercapacitors and photovoltaics
We demonstrate in this paper facile synthesis of CoS2 and NiS2 hollow spheres with various interiors through a solution-based route. The obtained CoS2 microspheres constructed by nanosheets display a three-dimensional ...
