Abstract：Thispaperprepared MMTGRcompositesubstratewithphysicalcompositemethod.Theirmicroscopicsurfacemorphology and specific surface area of materials were analyzed by TEM，BET，FT-IR.FeOOH- ∇⋅TiO2 nanofilm materials were prepared by the self -assembly method.A multiphase mineral system was constructed by the highly active nano -FeOOH-TiO2 composite membrane and modifiedlaymineralmatrix.Theinfluenceofsemiconductorcompositesandsubstratepropertiesontheirphotocatalyticpropertiswere discussed.Thesergisticandcyclicpromotionmechanismofteouplingofdsoption，catalysisandodationofpolutantsasre vealed.The experimental results could provide reference for the design of high-efficiency photocatalysts.
