Preparation of NiCo₂O₄ with Various Morphologies: a Review

Abstract

NiCo 2 O 4 nanomaterials exhibit great potential in the fields of energy storage and conversion especially in supercapacitors for their unique physicochemical properties. Given the important impact of morphology of nano material on its performance, this review focuses on preparation methods and application of NiCo 2 O 4 nanostructure with various morphologies including nanoneedle, nanowire, nanotube, nanosheet, sphere, nanoflower, coral-like structure and three-dimensional hybrid structure. Furthermore, the influence of morphology and particle size of NiCo 2 O 4 on its properties is also introduced. Finally, the future research direction of NiCo 2 O 4 nanomaterials in the fields of energy storage and conversion is prospected.
