“…The TEM image of the sample (Fig. 2c) reveals that the macroscopic porous morphology was composed of many nanoparticles.This may be the influence of the autogenic CO and CO 2 gas on the synthesis of microspheres [26]. During the heat treatment of precursor powder, the autogenic gas CO, CO 2 overflowed from the powder structure could destroy the original structure and refine the grains by reducing the agglomeration between ions and inhibiting the growth of grain.…”

The liquid phase reduction-heat treatment has been used to prepare V2O3nanoparticles in this paper. It is a novel method that the precursor was developed by Oxalic acid dehydrate (H2C2O4·2H2O) reduction of V2O5powder in anhydrous ethanol. V2O3nanoparticles were successfully obtained by thermal treatment of the precursor. The phase, composition, structure, and morphology of the as-obtained samples were verified by XRD, XPS, SEM and TEM measurements. Meanwhile, the possible formation mechanism of V2O3in the heat-treatment is briefly discussed by analyzing the DSC.

V2O3@C core‐shell structured nanorods (VCNR) were successfully prepared using V2O5 nanowires and glucose via a facile hydrothermal route combination of calcination. VCNR comprised of core‐shell structures with V2O3 cores and amorphous carbon shells. Electrochemical properties of VCNR as supercapacitor electrodes were studied in Na2SO4 neutral electrolyte. Results demonstrated that VCNR featured capacitive behavior originating from pseudocapacitance. Specific capacitances of VCNR at 0.5, 1, 2, 5 and 10 A⋅g−1 were achieved to 219, 192, 148, 127 and 119 F⋅g−1, respectively, and VCNR displayed higher specific capacitance than the values of carbon spheres and V2O3 particles. Maximum specific capacitance of VCNR reached 219 F⋅g−1 at 0.5 A⋅g−1 in present study, which was superior to the reported values of V2O3‐based materials and VO2‐based materials. Capacitance retention of VCNR was 100% after 700 cycles and 66% after 1000 cycles. Findings in present study proved that VCNR could be promising candidate as an ideal material for supercapacitors’ electrode.
