Zeolite-supported TiO 2 and Fe-doped TiO 2 /zeolite photocatalysts were synthesized, aiming at improving the adsorption properties of the microporous support towards polluting dyes and the photocatalytic performance of TiO 2 in the treatment of the adsorbed organics. The TiO 2 /HY zeolite catalyst exhibited the best performance in the photocatalytic degradation of methylene blue, MB, over 10 wt% TiO 2 /HY under UV light at 254 nm. The addition of Fe species in the synthesis mixture led to Fe-TiO 2 /HY catalyst. The combination of adequate zeolite, good titanium dioxide dispersion, and Fe doping led to a remarkable performance in the degradation of the model dye. Over a 10 wt% Fe-doped TiO 2 /HY catalyst a total removal of MB (>98%) was achieved after 60 min under very mild conditions and simple visible light irradiation.
