Intercrystal Self-Assembly for the Design of High-Quality Nickel Molybdate Nanocrystals

Abstract

Nanowire of nickel molybdate hydrate, being recognized as an emerging supercapacitor material, was synthesized from the intercrystal self-assembly process (commonly referred to as oriented aggregation or attachment). The detailed lattice image of a NiMoO₄·0.75H₂O nanowire and the intermediate nanostructure before reaching the interplanar binding were successfully captured by means of high-resolution transmission and scanning electron microscopies. NiMoO₄·0.75H₂O possessed highly crystalline surface and internal nanostructures
