NiO-Microflower Formed by Nanowire-weaving Nanosheets with Interconnected Ni-network Decoration as Supercapacitor Electrode.

ABSTRACT: We propose a 'weaving' evolution mechanism, by systematically investigating the products obtained in controlled experiments, to demonstrate the formation of Ni-based 'microflowers' which consists of multiple characteristic dimensions, in which the three dimensional (3D) NiO 'microflower' is constructed by a two-dimensional (2D) nanosheet framework that is derived from weaving one-dimensional (1D) nanowires. We found such unique nanostructures are conducive for the generation of an electrically conductive Ni-network on the nanosheet surface after being exposed to a reducing atmosphere. Our study offers a promising strategy to address the intrinsic issue of poor electrical conductivity for NiO-based materials with significant enhancement of utilization of NiO active materials, leading to a r
