Shape controlled synthesis of rod-like Co3O4 nanostructures as high-performance electrodes for supercapacitor applications

Reviews and Prospectives of Co3O4‐Based Nanomaterials for Supercapacitor Application

“…Hydrothermal method is widely used to synthesize nanostructured materials, which has the advantage of the easy control of size, morphology, crystal structure and low reaction temperature. V. Venkatachalam and co‐workers reported the synthesis of one dimensional electroactive material of Co 3 O 4 nanorods by hydrothermal method (Figure A−B). The specific surface area and pore diameter of rod‐like Co 3 O 4 electrode material are calculated as 38.6 m 2 g −1 and 3.45 nm, respectively (Figure C).…”

Recent Advance in Co3O4 and Co3O4-Containing Electrode Materials for High-Performance Supercapacitors

“…Hydrothermal reaction has been widely used for the synthesis of Co 3 O 4 nanomaterials. For example, one-dimensional (1D) nanorod-like Co 3 O 4 was successfully synthesized via the hydrothermal method [36]. It had a high Cs of 655 F•g −1 at a current density of 0.5 A•g −1 and also exhibited a high capacitance retention and a better cycling stability.…”

Three-dimensional TiNb2O7 anchored on carbon nanofiber core–shell arrays as an anode for high-rate lithium ion storage

“…11,12 The nanoparticles are clustered together to minimize their surface area, thus reducing their advantages as nanostructures with high surface to volume ratios, and making them unsuitable as a major component for rechargeable LIBs that require high capacity and long-term stability. [13][14][15][16] Onedimensional (1D) nanomaterials, 17 such as nanowires (NWs), 18 nanorods (NRs), 19,20 nanobers (NFs) 21 and nanotubes (NTs), 22,23 with high surface areas, due to their unique physical and chemical properties have attracted extensive attention, and the advantages of these nanostructures have been widely utilized in recent years. On the other hand, when nanoparticles are composited with 1D nanomaterials, the three-dimensional heterostructure nanomaterials could get high surface to volume ratios.…”
