Core-shell structured CuCo2S4@CoMoO4 nanorods for advanced electrode materials

Recent Progress in Core@Shell Sulfide Electrode Materials for Advanced Supercapacitor Devices

“…Also, most of the shell materials in the bimetallic core@shell structures with metal sulfide core are metal oxides. The bimetallic sulfide cores have been prepared by hydrothermal method in several shapes such as nanowires, nanosheets, nanotubes, among others, [35,42–43,59] but electrodeposition is the technique of choice when it comes to preparing tightly connected shell materials based on bimetallic sulfides directly on the core material, especially as high surface area nanosheets, due to the possibility of controlling the amount of deposited material by the amount of charge.…”

“…The bimetallic sulfide cores have been synthesized by hydrothermal method in several shapes such as nanowires, nanosheets, nanotubes, among others [35,42–43,59] . Generally, those nanostructures are grown on substrates like nickel foam (NF) and carbon cloth (CC), since they act as a high surface area conducting skeleton to support the bimetallic sulfide core structure.…”

“…Other bimetallic sulfides such as CuCo 2 S 4 , FeCo 2 S 4 , and CoFe 2 S 4 have been used as core materials [42–43,45,59] . Mao et al [42] .…”

“…Other bimetallic sulfides such as CuCo 2 S 4 , FeCo 2 S 4 , and CoFe 2 S 4 have been used as core materials [42–43,45,59] . Mao et al [42] . obtained a CuCo 2 S 4 @CoMoO 4 material on NF substrate using a hydrothermal method followed by a calcination process.…”

Hydrothermal Synthesis of Hierarchical CoMoO4 Nanostructures

“…In recent years, there has been an active growth in the interest of the scientific community in the study of approaches to the formation of nanomaterials of various types (primarily 0D and 2D) with a hierarchically organized microstructure (including those consisting of anisotropically oriented particles), which, as a rule, leads to a significant improvement in their target characteristics. In particular, it was shown [17,18] that obtaining an active material of electrodes in the form of one-dimensional hierarchical structures (nanorods [19][20][21][22], nanofibers [23][24][25][26], nanotubes [27][28][29][30], nanowires [31][32][33][34], nanosheets [35,36], microspheres [35][36][37][38][39], etc.) makes it possible to increase the electrical conductivity of the electrode itself, as well as to create supercapacitors with a high capacity and specific power.…”
