Synthesis of Fe3O4/TiO2 secondary heterostructures Figure 1 systematically demonstrates the preparation process of Fe3O4/TiO2 secondary heterostructures, mainly including electrospinning technology and hydrothermal method. Obviously, one-dimensional
In order to confirm that the metal oxide/TiO2 secondary heterostructure is an excellent electrode material for lithium ion batteries, we took the Co3O4/TiO2 secondary heterostructure
Morphology analysis of Co3O4/TiO2 secondary heterostructures Four metal oxides (Co2O4, Fe2O3, Fe3O4, and CuO) can be grown as secondary structures on the surface of TiO2
Preparation of Co3O4/TiO2 secondary heterostructures (1) Preparation of TiO2 nanofibersA certain amount of PVP was weighed into 5 mL of ethanol and 1 mL of
Next, we investigate the electrochemical performance of porous Fe2O3 nanotubes as anode materials for Li-ion batteries. Cyclic voltammetry is a direct and effective method to
Morphology analysis of porous Fe2O3 nanotubes Figure 1 shows the SEM images of electrospinning nanofibers and porous Fe2O3 nanotubes. From Fig. 1, we can see
1.preparation method of porous Fe2O3 nanotubes Weigh a certain mass of polyvinylpyrrolidone and dissolve it in N, N-dimethylformamide. When stirring at room temperature for 12h,
1. Synthesis of V2O5 nanomaterials with different morphologiesFigure 1 shows the synthesis process of V2O5 nanomaterials with different morphologies. First, non-woven films were prepared by
Since Whittingham et al. first reported the reversible electrochemical performance of lithium ions intercalated into V2O5 structure in 1976, V2O5 has been used as a
