Abstract


Zinc Oxide (ZnO) is used widely for the photodegradation, application due to its superior photocatalytic oxidation ability, non photocorrosive and non-toxic nature. However, due to their low photons adsorption capability and rapid electron hole pair recombination limits its applications. In here, chitosan (CS) was introduced as a support material to improve photocatalytic activity. ZnO-CS hybrid catalyst was synthesized via simple ex-situ method with different condition. The structural and morphological properties of ZnO/CS hybrid photocatalyst will be further analyzed through X-ray diffractometer (XRD). Meanwhile, the interaction of ZnO to CS matrix is analyzed by FTIR. Furthermore, the photodegradation of methyl orange (MO) as a model of synthetic dyes shown that, the adsorption reached to 85 %, while optimally photocatalytic obtained at 6 g with ZnO in dry feature.
