Embodiment Construction

[0017] In the present invention 2 o 3 The preparation method of hollow shape nano-tetrahedral structure comprises the following steps:

[0018] 1. Preparation of titanate nanofibers by hydrothermal method:

[0019] Put the titanium sheet in acetone for ultrasonic cleaning for 8-10 minutes, and then put it in a drying oven to dry. Tilt the titanium sheet into the cleaned reactor and immerse it in NaOH solution with a concentration of 2mol / L. Put the reaction kettle in a resistance furnace and heat it at 220°C-240°C for 2-10 hours, then cool down naturally. The titanium sheet was taken out, rinsed with distilled water, and dried to obtain the desired titanate nanofiber substrate.

[0020] 2. Preparation of In by magnetron sputtering 2 o 3 Hollow nano-tetrahedral structure:

[0021] Place the target and titanate nanofiber substrate in the KCCK-III multi-target magnetron sputtering apparatus, adjust the target step distance to 3cm-4cm (to control the normal sputtering rate ...
