摘要：NOVELTY - The preparation method of Z-type photocatalytic material involves dispersing bismuth vanadate microcrystals in aqueous solution, uniformly mixing, adding silver nitrate to the mixture and then stirring, irradiating the mixture for 3 hours and then centrifuging, washing the mixture and then precipitating, removing impurity ions and then drying to obtain bismuth vanadate-silver, dissolving bismuth vanadate-silver in aqueous solution, adding ferric nitrate solution and potassium bromide solution to the mixture and then reacting, centrifuging the mixture, and washing. USE - The method is useful for preparation of Z-type photocatalytic material, which is useful for degradation of environmental pollutants such as tetracycline. ADVANTAGE - The method enables simple preparation of Z-type photocatalytic material in short period. DETAILED DESCRIPTION - The preparation method of Z-type photocatalytic material involves dispersing bismuth vanadate microcrystals in aqueous solution, uniformly mixing, adding silver nitrate to the mixture and then stirring, irradiating the mixture for 3 hours and then centrifuging, washing the mixture and then precipitating, removing impurity ions and then drying to obtain bismuth vanadate-silver, dissolving bismuth vanadate-silver in aqueous solution, adding ferric nitrate solution and potassium bromide solution to the mixture and then reacting for 1 hour, centrifuging the mixture, and washing.
