Abstract
New titanosilicates of various framework topologies were synthesized using TEAOH template. This Ivanyukite (Na-2[Ti4O2(OH)(2)(SiO4)(3)]center dot 6H(2)O) and Sitinakite (H4.04Na1.64O8.84SiTi2) zeolites were synthesized hydrothermally and considered to be under Pharmacosiderite phases. Various conditions were investigated (i.e temperature, aging time and alkalinity), and the success was examined by using XRD, IR and SEM technologies. Due to the large effect of dyes on pollution and their toxicity, Malachite green dye used. The photocatalytic effect of the prepared zeolites were studied in the decomposition of dye, and it was found with high photocatalytic activity may approach 96%.
