Embodiment 1
[0033] Example 1: γ-MnO 2 Preparation of nanotubes / nanowires
[0034] At room temperature, the MnSO 4 Solution (100mL, 1M) was added dropwise to methanol solution (100mL, 1M), then NaOH solution (100mL, 1M) was added, after mixing evenly, it was transferred to a 1L stainless steel autoclave, and reacted at 120°C for 20 hours, and the reaction was completed After cooling to room temperature, washing with distilled water and absolute ethanol several times, and vacuum drying at 60°C for 4 hours, the γ-MnO 2 Nanotubes / Nanowires. Generate γ-MnO 2 The chemical reactions involved in nanotubes / nanowires are as follows:

Embodiment 2
[0037] γ-MnO prepared by the method described in Example 1 2 The XRD patterns of nanotubes / nanowires are as follows figure 1 as shown in a. According to the position and intensity of the characteristic peaks in the spectrogram, the unit cell parameters are calculated as a=6.366, b=10.15, c=4.089, belonging to the orthorhombic system, and the intensity and position of the diffraction peaks are the same as those of the JCPDS standard card (No. 14-0644, a=6.36 , b=10.15 , c=4.09 ), and there is no heterophase diffraction peak, indicating that γ-MnO with higher purity was obtained 2 . The broadening of the diffraction peaks is due to the fact that the product is nanoscale and the crystal grains are extremely fine.
[0038] MnO 2 The basic structural unit is [MnO 6 ] octahedron ( figure 1 b), in γ-MnO 2 MnO 6 ] octahedra are connected to adjacent octahedra by edges or corners, forming a unique double-chain and single-chain alternate structure, that is, [1×1] and [1×2] tu...
Embodiment 3
[0040] γ-MnO prepared by the method described in Example 1 2 SEM analysis of nanotubes / nanowires ( figure 2 a) show that: the product is an aggregate of nanotubes and nanowires, the ratio of nanotubes and nanowires is about 40% and 60%, the length of a single nanotube or nanowire is 2-4 μm, and the diameter is 75-85nm, further The enlarged SEM analysis can observe the open tubular structure of nanotubes, and the thickness of the tube wall is about 20nm ( figure 2 b). TEM analysis ( figure 2 c) It is further confirmed that the product is an aggregate of nanowires and nanotubes. Single γ-MnO 2 HRTEM analysis of nanowires ( figure 2 d) shows that the product has good crystallinity and uniform stripe width, and the interlayer spacing is about 0.213nm, which is similar to that of γ-MnO 2 The (002) interplanar spacing is consistent.
