The invention provides a preparation method of a chalcogenide semiconductor CdX composite H- TiO2 -based nanotube array, belonging to the technical field of nanocomposite materials. The steps of the specific preparation method are as follows: on the titanium-containing metal substrate, an ordered array of nanotubes is prepared by anodic oxidation; after crystallization treatment is performed on the prepared TiO2 ordered array of nanotubes, surface hydrogenation treatment is carried out to obtain H ‑TiO2-based nanotube array; the prepared H‑ TiO2 - based nanotube array is compounded with chalcogenide semiconductor CdX to prepare a chalcogenide semiconductor CdX-composite H‑ TiO2 -based nanotube array. The TiO 2 nanotube array composite material has cheap and easy-to-obtain raw materials, simple preparation method, highly ordered structure, high specific surface area, stable chemical properties, good photocatalytic performance, and high photoconversion rate. It can not only be used as a photogenerated cathodic protection It can also be used as a material for photocatalytic degradation of pollutants. |
