| Abstract: | In synthesis of TS 2 zeolite with silica sol as silicon source, addition of a small quantity of Al into the sol could effectively reduce the amount of template TBAOH. When n (TBAOH)/ n (SiO 2) is lower than 0.1, TS 2 with fair catalytic activity was still synthesized , and the reaction time of phenol hydroxylation could be greatly decreased than TS 2 reported. TS 2 samples were characterized by XRD,IR and ICP. |
