Three-dimensional flower-like hybrid BiOI-zeolite composites were synthesized via a simple, facile and environmentally-benign hydrothermal method. And the synthetic mechanism of the flower-like BiOI-zeolite hierarchical structures was discussed. The as-obtained BiOI-zeolite samples exhibited excellent performance in the degradation of methylene blue solution under visible light irradiation. The influence of different Bi/I molar ratios and surfactants was studied. The degradation rate of MB by BiOI-zeolite composite photocatalysts can reach 94.8% under visible light irradiation for 10 min, when the Bi/I molar ratio is 1:1 and is surfactant free. This implies its huge application potential as photocatalysts in degradation of pollutants under visible light.
