The invention discloses a nickel-doped titanium oxide cluster nano-catalytic material, a preparation method and application, including preparing titanium oxide cluster powder by using pivalic acid as a precursor; then adding the titanium oxide cluster powder and nickel chloride into water to dissolve and irradiating with a mercury lamp to react to obtain a nickel-doped titanium oxide cluster nano-catalytic material, and the mass ratio of the titanium oxide cluster powder to nickel chloride is 20-30:1. The nickel-doped composite titanium oxide cluster nanocatalytic material prepared by the invention has a series of outstanding advantages: the photocatalytic oxidation technology has low cost, environmental protection, easy operation, high degradation efficiency, and many kinds of degraded tetracyclines; the composite photocatalyst overcomes the Single-molecule photocatalysts have disadvantages such as poor quantum efficiency, poor visible light absorption efficiency, and easy photo-induced charge combination; titanium-oxygen clusters have large specific surface area, easy to form vacuum sites under light conditions, have more pores, and have high catalytic performance. . |
