▎ 摘 要
NOVELTY - Recyclable and high efficiency photocatalytic materials, obtained by introducing graphene oxide material, using anionic natural polymer polysaccharide aqueous solution and divalent cation to form a stable gel, using chemical coupling and in-situ deposition to loading silver chloride and preparing silver doped silver chloride/ graphite oxide photocatalytic material. USE - The photocatalytic material is useful in preparing photocatalyst and degrading rhodamine B, methylene blue, methyl orange and degrading tetracycline (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing recyclable high-efficiency photocatalytic material comprising (i) taking graphene oxide dispersion liquid, adding sodium alginate or potassium alginate solution and ultrasonically dispersing to completely mixing, (ii) adding hexadecyl trimethyl ammonium bromide into the mixed solution and ultrasonically dispersing, (iii) under stirring, dropping silver nitrate solution, and continuously stirring, (iv) under stirring, dropping calcium chloride solution in the suspension forming insoluble small particles, stirring and allowing to stand, and (v) filtering gauze washing the small particle precipitate with aqueous, adding the small particle precipitate into the container, adding aqueous, under stirring and placing in the sun illumination or irradiation under the xenon light source, gauze filtering, washing with aqueous, vacuum freezing and drying to obtain the silver doped silver chloride/ graphite oxide photocatalytic material.
