Hydrothermal synthesis of Co3O4 nanoparticles decorated three dimensional MoS2 nanoflower for exceptionally stable supercapacitor electrode with improved capacitive performance

Defect mediated visible light induced photocatalytic activity of Co3O4 nanoparticle decorated MoS2 nanoflower: A combined experimental and theoretical study

“…The crystallite size of MoS 2 @Co 3 O 4 nanocomposite got reduced because of the decoration of nanoparticles. The displacements of atoms in the nanocomposite created lattice defects and produced microstrain [ 53 ]. The microstrain ( ε ) of MoS 2 and MoS 2 @Co 3 O 4 nanocomposite were measured by the formulation [ 54 ].…”

“…Due to the low band gap, the nanocomposite is active in the visible light region and improves the photocatalytic performance. Moreover, the incorporated Co 3 O 4 (4 wt%) nanoparticles create defects in the crystal structure that can trap electrons least charge resistance thus photocatalytic properties are enhanced by electron-hole separation and the development of the Schottky barrier at the interface of the composite [ 26 , 27 ].…”

“…However, the synthesis of MoS 2 nanosheet requires painstaking processes and provides low yields, which might limit the widespread applications. In this regard, MoS 2 nanoflowers are fabricated using low-cost one-step hydrothermal synthesis because other methods, such as green synthesis, do not control morphology and give a low amount of yield, but hydrothermal processing may offer a cost-effective route for the production of high-yield of MoS 2 [ 27 , 31 ].…”

DFT-aided experimental investigation on the electrochemical performance of hetero-interface-functionalized CuO nanoparticle-decorated MoS2 nanoflowers for energy storage applications

“…10,11 Different metal oxide nanoparticles, including NiO, MnO 2 , TiO 2 , and Co 3 O 4 , have been incorporated to improve the electrochemical properties of MoS 2 nanomaterials. [11][12][13][14] Wang et al 15 reported the synthesis of MoS 2 / Mn 3 O 4 composite nanomaterials by a combined hydrothermal and chemical precipitation method. They found that incorporating Mn 3 O 4 improved the capacitance of layer-structured MoS 2 from 47.2 F g À1 to 119.3 F g À1 .…”

Bimetallic CoMoO4 Nanosheets on Freestanding Nanofiber as Wearable Supercapacitors with Long-Term Stability

“…Freestanding binder-free CNFs decorated with ZIF-67-derived dodecahedral CoO x have been used in supercapacitors [26,27]. In other studies, the only decoration material used was cobalt oxide from ZIF-67, and the use of bimetallic materials would have resulted in superior supercapacitor performance [28,29]. Bimetallic oxides with multivalent oxidation states facilitate the rapid transfer of electrolytic ions owing to the enhanced electron mobility between the two metals and efficient Faradaic reactions [23,24,30,31].…”
