Hierarchical 3D-flower-like CuO nanostructure on copper foil for supercapacitors

Abstract

We present a novel route for the synthesis of CuO thin films. The nano-flower like nanostructures provide high surface area, and the CuO shows excellent supercapacitive properties.

Recent Advancements in the Cobalt Oxides, Manganese Oxides, and Their Composite As an Electrode Material for Supercapacitor: A Review

“…These are the basis of a variety of functional materials (Shinde et al, 2015). Among the various supercapacitor electrode materials, transition metal oxides offer high electronegativity, rich redox reactions, low cost, environmental friendliness, and excellent electrochemical performance.…”

Designing a Copper‐ and Silver‐Sulfide Composite with Co3O4 for High‐Performance Electrochemical Supercapacitors

“…To achieve this, various architectures of electrodes with reasonable designs consisting of composites of hybrid structures is an effective way. While searching for an improved design of an electrode architecture to boost the specific capacitance of pseudocapacitors, various conductive substrates, such as copper, nickel, carbon fabric, and poly(ethylene terephthalate) are used . Rakhi et al.…”

“…While searching for an improved design of an electrode architecture to boost the specific capacitance of pseudocapacitors, various conductive substrates, such as copper, nickel, carbon fabric, and poly (ethylene terephthalate) are used. [28][29][30][31] Rakhi et al used hydrous RuO 2 nanoparticle decoration on a Co 3 O 4 nanosheet and obtained a specific capacitance of 905 F g À 1 . [32] The use of RuO 2 is not eco-friendly and is expensive.…”

Formation of urchin-like CuO structure through thermal oxidation and its field-emission lighting application

“…Liu and Zeng [40] fabricated dandelion-like CuO by using the hydrothermal method. Many similar structures, such as hierarchical CuO [41][42][43] and urchin-like CuO [44][45][46], were later fabricated using the hydrothermal synthetic route. In addition, thermal decomposition [47], solid stabilized emulsion [48], and a facile reflux method [49] have been applied in forming urchin-like CuO structures.…”
