the invention relates to a method for synthesizing a family of zeolite materials , grouped together under the name itq - 16 , in an oh − medium and in the absence of fluorides and to the catalytic applications thereof . the zeolite itq - 16 family of materials is characterized by having different proportions of distinct polymorphs a , b and c described as possible intergrowths in the beta zeolite and , therefore , the x - ray diffraction patterns of said family are different from that described for the beta zeolite . in its calcinated form , zeolite itq - 16 has the following empirical formula : x : tto 2 : ggeo 2 : sio 2 , wherein t is one or more elements having + 4 oxidation status and different from ge and si ; x is one or more elements having + 3 oxidation status ; and m can be h + or one or more inorganic cations with a + n charge .
