The invention provides a silicon bismuth oxyhalide material and a preparation method and application thereof. The general formula of the silicon bismuth oxyhalide material is BiSiOX a I b , wherein X=Cl or Br, 0.5≤a≤2, 0≤b≤ 1, it is prepared by the following method: take the inorganic salt of bismuth as the reaction raw material, take the silanized eutectic solvent or the silanized ionic liquid as the reaction solvent, after dissolving the reaction raw material in the reaction solvent, at pH 7~9 It is obtained after solvothermal reaction at 70~80℃ for 18~24h, solid-liquid separation, washing and drying. The silicon bismuth oxyhalide material prepared by the invention has large specific surface area, good adsorption performance, improves the separation efficiency of photogenerated electrons and holes, prolongs the life of carriers, has high photocatalytic activity, strong oxidizing ability and good stability It can be used for adsorption and catalytic removal of various endocrine disruptors in environmental water, and has broad application prospects. |
