In the present work, we report the use of zeolite NH4-ZSM-11 and H-ZSM-11 as the supportfor the in situ generation of titania from an alcoholic solution of titanium isopropoxide, followedby calcination. The resulting catalyst systems were characterized by a series of complementarytechniques: X-ray diffraction spectrometry (XRD), transmittance Fourier transform infrared spectroscopy(FTIR) and BET surface area. The supported catalysts were evaluated for their activityin the photodecomposition of the insecticide dichlorvos (DDVP).
