Water pollution appears to be one of the greatest challenges the humane society is currently facing [1]. Here, we report the preparation of a new hybrid material based on Bi5O7I supported on chitosan and its application in organic dye photo-degradation and 4-Nitrophenol reduction. The composition, structure and morphology of the obtained hybrid materials were investigated using SEM, EDS, Uv-Vis DRS, XRD, FTIR and Raman spectroscopy. Photocatalytic experiments revealed that these materials have an excellent photocatalytic for degradation of methyl orange in aqueous media. Moreover, the materials showed a good performance in 4-nitrrophenol reduction using NaBH4 as reducing agent. More importantly, the photocatalysts could easily be recovered by simple filtration with no significant loss of their activity after many successive runs.
