The present invention relates to a Z-type photocatalyst utilizing efficient one-dimensional plasma effect and its preparation method and application. The Z-type photocatalyst is prepared by the following method: S1: Dissolving In salt and alkali, stirring and mixing evenly, and reacting to obtain In(OH) 3 powder; S2: calcining the In(OH) 3 powder at 200-300° C. , to obtain In 2 O 3 nanorods; S3: ultrasonically disperse the In 2 O 3 nanorods, add Ag salt, stir, and ultrasonically obtain an Ag + doped In 2 O 3 aqueous dispersion; S4: add Ag + doped In 2 O 3 The Z-type photocatalyst is obtained by adding Cl salt to the mixed In 2 O 3 aqueous dispersion until the mixture is uniform, and performing a photoreduction reaction under illumination. The Z-type photocatalyst provided by the invention has suitable band gap, good response, high utilization rate of sunlight, and strong photocatalytic degradation activity for tetracycline compounds, and has good performance in today's overuse of antibiotics. Practical application and marketing value. |
