The invention discloses a method for preparing silver-carried silica microsphere functional materials. Monodisperse uniform spherical composite metallic silver-carried silica functional particles are prepared by chemical etching and metal salt pyrolysis methods, the particles are formed by uniformly loading nanometer metallic silver with the grain diameter of 5-50nm on the monodisperse multihole silica particles used as inner cores, so that the original silica particles have the special properties of nanometer silver particles. The particle obtained by the method has high purity and good monodispersity, the size of a product can be controlled by reaction conditions, and the method has wide application prospects. The method for preparing the silver-carried silica microsphere functional materials disclosed by the invention has a simple process and is environment-friendly, raw materials and equipment are cheap and are easy to obtain, and the cost is low. The synthesis time is short, the efficient is high, and the method has great industrial production prospects.
