摘要: Zeolite-supported TiO2 and Fe-doped TiO2/zeolite photocatalysts were synthesized, aiming at improving the adsorption properties of microporous support towards polluting dyes photocatalytic performance in treatment adsorbed organics. The TiO2/HY zeolite catalyst exhibited best degradation methylene blue, MB, over 10 wt% under UV light 254 nm. addition Fe species synthesis mixture led to Fe-TiO2/HY catalyst. combination adequate zeolite, good titanium dioxide dispersion, doping a remarkable model dye. Over total removal MB (>98%) was achieved after 60 min very mild conditions simple visible irradiation.
