摘　　要：The photochemical behavior of polyoxometalates（POMs）have been studied extensivelyIn homogeneous solutions［1-3]．However，the major drawback to the practical applications ofthe homogeneous systems is the high water solubility of POMs，which impedes the readyrecovery and the reuse of the photocatalysts．Therefore，the preparation of insoluble POMs Isconsidered．More recently，we haveprepared insoluble POMs，i．e，Keggin－type microporousPOMs，H3PW12O40／SiO2 or H4SiW12O40／SiO2，and paratungstate A－containing pillaredcompound，Mg12Al6（OH）36（W7O24）·4H2O，for the purpose of photo－oxidation of aqueous
