Hierarchical foam of exposed ultrathin nickel nanosheets supported on chainlike Ni-nanowires and the derivative chalcogenide for enhanced pseudocapacitance.
Foamlike nickel hierarchical structures of ultrathin nanosheets supported on thin wires composed of nanoparticles are prepared by a facile one-pot synthesis via controlled nucleation and growth process. By further sulfidation, the sulfide derivative of loose porous fibrous structure shows a high electrochemical capacity for potential pseudocapacitor applications.
