Embodiment 1
[0024] (1) if figure 1 As mentioned above, take the length and width as 2×6 cm 2 Titanium sheet folded into figure 1 The shape shown was ultrasonically cleaned with acetone for 30 minutes, then ultrasonically cleaned with deionized water, and then etched with a mixed acid solution of hydrofluoric acid: nitric acid: deionized water with a volume ratio of 1:3:6 for one minute, and finally Ultrasonic cleaning and drying with deionized water to obtain titanium metal sheets with clean surfaces;
[0025] (2) Put the corundum boat containing 2 grams of titanium dioxide powder and the metal titanium sheet etched in step (1) into the tube furnace together, and place it as figure 1 shown;
[0026] (3) Pre-flow nitrogen for 2 hours at a nitrogen flow rate of 100 mL / min, turn off the nitrogen gas, and pass hydrogen gas for 30 minutes at a hydrogen flow rate of 100 mL / min. Then, adjust the hydrogen flow rate to 50 mL / min, raise the temperature to 1050 °C at a rate of 8 °C / min, keep ...
Embodiment 2
[0031] The difference between this example and Example 1 is that 10% oxalic acid solution is used and etched at 100°C for 2 hours. The other steps are the same as in Example 1. The obtained Magnéli phase titanium oxide nanowire is similar to the product of Example 1. Its XRD pattern and scan Electron microscope pictures can refer to figure 2 , image 3 .
Embodiment 3
[0033] The difference between this example and Example 1 is that the hydrogen flow rate is adjusted to 20 mL / min during the heat preservation, and the other steps are the same as in Example 1. The obtained Magnéli phase titanium oxide nanowire has a morphology similar to that of Example 1, and the diameter ratio is slightly smaller than that of Example 1. Product nanowires, its XRD pattern and scanning electron microscope pattern can refer to figure 2 , image 3 .
