The present application provides a method for preparing a near-infrared light-responsive titanium-based material, comprising: placing a pretreated titanium-based precursor in an alkaline solution to perform a first hydrothermal reaction to obtain a titanium-based substrate, wherein the first hydrothermal The reaction temperature is 60°C-300°C, the time is 2h-24h, and the concentration of the alkali solution is 0.5M-10M; the titanium base is placed in an acid solution to carry out the second hydrothermal reaction to obtain a near-infrared light-responsive titanium base Material, the near-infrared light-responsive titanium-based material includes a titanium substrate and a plurality of titanium oxide nanorods arranged on the surface of the titanium substrate, wherein the temperature of the second hydrothermal reaction is greater than or equal to 120 ° C, the time is greater than or equal to 3h, the acid solution The concentration is 0.01M‑0.5M. The near-infrared light-responsive titanium-based material prepared by the preparation method has near-infrared light absorption and photocatalytic ability, antibacterial effect and excellent biocompatibility. The present application also provides near-infrared light-responsive titanium-based materials and applications thereof. |
